Bing launches visually-driven iPad app

Posted: 07 Apr 2011 09:30 AM PDT

Microsoft has launched Bing for iPad, a tablet-specific version of its free iPhone app.

The visual-conscious search engine takes full advantage of the larger screen display, with the Bing homepage images displayed in all their glory.

In terms of features, Bing for iPad is largely the same as its iPhone equivalent, and the Bing search bar is ever-present at the top of the app.

Bing-a-ling

As well as being able to, y'know, search the internet, the app allows you to swipe your way between touch-enabled listings, including news, local business results and trending topics.

Bing Local and Map integration also offer bird's eye directions and real-time traffic information.

If typing on the iPad is too much of a chore, the app also comes with voice activated search and image searches are returned in a grid view much like, er, Google's.

No doubt Microsoft's plan is to lure iPad users away from Safari and its default Google search with this luscious new tablet app. Good luck with that.

Rumour: Sony NGP price, name and launch games at E3 2011

Posted: 07 Apr 2011 09:23 AM PDT

Sony is rumoured to be planning a major Next Generation Portable (NGP) showing at E3 2011 in Los Angeles this coming June, revealing the final name, pricing details and game launch line-up, according to latest games industry leaks.

As well as the Sony NGP pricing and name reveal at E3, an apparent source at Sony France has also claimed that a new Polyphony title will arrive on the handheld before March 2012.

The news, which really does have to be filed under 'E3 rumours' right now, comes from a Gamekult forum poster, who is apparently a reliable source of games industry news, according to VG247 and numerous other reliable industry news outlets.

Loads of new NGP games

While it is no great shock to hear that Sony may well unveil the final consumer marketing plans for the successor to the PlayStation Portable at E3 this year, it is interesting to hear the latest speculation that there will be a total of seven first party Sony game titles announced for the new handheld in LA, along with a host of new games from third-party publishers such as Konami and others.

The forum poster suggests we should see an NGP port of the critically-acclaimed PSP title Metal Gear Solid: Peace Walker, as well as further new Metal Gear announcements from Konami and new game announcements from Gran Turismo developer Polyphony at E3 this coming June.

We've contacted Sony Computer Entertainment Europe for further comment for its plans for E3 2011. Stay tuned!

Updated: 15 best graphics cards in the world today

Posted: 07 Apr 2011 08:39 AM PDT

The PC is lining up for a brilliant year. It's already been highlighted as the platform of choice for for the likes of Bulletstorm, Crysis 2 and Dragon Age 2 to name but a few. And as the consoles stagnate due to their ageing technology, it's something that's only set to continue.

In order to experience such games at their best though, you're going to need to ensure you have a machine that's up to the task. And by machine we're primarily focusing on your graphics card.

It's the graphics card that does the serious work when it comes to rendering your games, and the more effects and higher resolutions you throw at it, the more is asked of that graphics card.

It's important to pick your graphics card so that it works well with your display, or displays. There's no point for instance, trying to power a 30-inch screen with the likes of a GeForce GTS 450. By the same notion, running a standard 20-inch screen with the likes of Radeon HD 6990 won't begin to tap into the cards power.

As a quick rule of thumb, whatever you spent on your screen, you're going to want to spend a similar amount to power it. Roughly.

The question is, which one of the many graphics cards out there should you actually spend your hard earned cash on? Here TechRadar highlights the top fifteen cards worth considering. We cover the notable cards from the last generation, the best all-rounders for most PC gamers, and the £550 monsters that can handle multi-screen outputs.

In this guide though we'll let you know what's hot, what's cool and what the fastest GPUs available right now and worthy of your time are.

Best of all, because we're now enjoying the second generation of DirectX 11 hardware, every card we look at here is capable of rendering the latest, funkiest DirectX 11 games.

So how does your graphics card stand in our countdown, and is it time for an upgrade? Well, there's only one way to find out…

ATI radeon hd 5970

There are a lot of terms and acronyms that get bandied around when talking about graphics cards, and not a lot of explanation to go along with them.

Before we delve into the meat of the feature let's take a minute to clear things up a little.

GPU - This is the graphics processing unit, the chip at the heart of the graphics card. Many cards use the same GPU but partner it with different components and at different clockspeeds to produce slower or faster graphics cards.

GDDR - Graphics Double Data Rate memory is the specific kind of memory that is used on graphics cards.

ROPs - The Render Output unit comes into play during the final stages in the rendering process, bringing together the data from each of the memory buffers in the graphics card's local memory. The more of them you have, the better off you are.

CUDA - The Compute Unified Device Architecture is a coding language Nvidia invented to allow parallel computing on its range of GPUs. From its 8 series upwards all its cards can use CUDA to speed up parallel processing applications, such as video encoding, in a faster way than your computer's CPU.

PhysX - Originally an accelerator chip and software layer from the small company Ageia, Nvidia bought up PhysX and has now applied it to its GPUs, again from the 8 series forward. It allows for more advanced physics simulations, such as liquid or cloth, in games that have been coded with the PhysX software included.

Crossfire and SLI - These are the relevant multi-GPU configurations from both AMD and Nvidia. Both allow multiple graphics cards to be connected together to increase the rendering performance. Historically this has been fraught with driver issues and diminishing returns for the extra cards, but as the latest cards have been released we are getting closer to doubling the performance by adding in a second card.

PCB - The Printed Circuit Board is the physical board that graphics cards (and all other micro-electronics) have their components attached to. The boards are printed with conductive pathways between the relevant components instead of using physical wires.

DirectX - Microsoft's DirectX is a collection of its own proprietary APIs (application programming interfaces) for dealing with multimedia tasks on its own operating systems. The Direct3D part is specifically to do with 3D graphics and utilises hardware acceleration if there is a GPU in place to take advantage of it.

Tesselation - This is one of the key buzzwords to come from Microsoft's latest graphical API, DirectX 11. Essentially it is designed to add extra geometry to a simple polygon using displacement maps to tell the GPU where to raise and lower parts of the polygon as the graphics card computes the data. The idea being to add geometry to objects in a game world without significantly impairing performance and it is set to become a key battleground in the graphics war in the coming years.

The first generation of DirectX 11 graphics cards boasted some notable GPUs. Here's are low-down of the cards that still manage to be relevant even after the second slew of cards settles in:

5. Nvidia GeForce GTS 450 (£85)

Best graphics cards

If 1680 x 1050 is the mass-market gaming resolution of choice, then the GTS 450 is opium for the masses.

This tiny powerhouse (well, it's still dual-width, but pleasingly short) is capable of feats beyond its £80-£90 price tag. What's more, in SLI, you'll see massive performance gains, making the dual-card upgrade path a realistic and impressive option for budget systems.

The basic GeForce GTS 450 is, architecturally, about half of a GeForce 460 with a higher clockspeed and a narrower memory bus.

However, the GTS 450 has the advantage over the GTX 460 of being smaller and requiring less power, which makes it a strong candidate for that SLI set-up

It is, however, now pitched directly up against the HD 5750 in pricing terms thanks to the on-going Nvidia/AMD graphics card price wars. And that is a card the GTS 450 happily beats into submission in any benchmark you throw at it.

4. AMD Radeon HD 5770 (£100)

best graphics cards

For budget-conscious gamers, the HD 5770 should be a serious consideration. Have a scout around the online retailers, and you'll see that examples can be had for less than £100 now.

Offering competent performance at the mainstream 22-inch resolution of 1680 x 1050, it also comes with the promise of cool-running, quiet operation – a trademark of AMD's last-gen design philosophy.

However, try to crank the shinier graphical elements – such as Anti-Aliasing and Anisotropic Filtering – too high, and the card starts to run out of grunt.

AMD's EyeFinity technology, which enables multi-screen scaling, is a very real option with the 5770, though we wouldn't recommend the 5770 for multi-screen gaming; it just doesn't have the throughput for gaming at huge resolutions.

But the really interesting thing about the HD 5770 is what its price represents. At these low prices, our thoughts turn to CrossFire setups. For under £200, you can net yourself a twin-card setup that offers kick-ass performance at mid-range resolutions.

If you're content with that 22-inch monitor and want zingy performance on a budget, this CF setup is probably the cheapest way to achieve it... Oh, and did we mention the 5770 is DX11 capable? Yum.

3. Nvidia GeForce GTX 470 (£160)

best graphics card

Not so hot on the heels of Nvidia's first DX11 graphics cards came the GeForce GTX 470, a cut-down version of the GF100 GPU the green company is rightfully proud of.

Given the larger pricetag of its big brother, the GTX 480, this represents the most affordable high-end Fermi card of the first generation.

Like the rest of the Fermi range, the 470 has seen some nifty price-cuts, which means it can now be had for £160. This makes the cheapest 470s at just £30 more expensive than the GTX 460 1GB, the new midrange king. That makes it a pretty compelling prospect right now.

In addition, at the native 22-inch resolution of 1680 x 1050, this card is a fair way ahead of the HD 5870. When things get cranked up though, it starts to lose its competitive edge against AMD's upper-midrange peer.

Indeed, in our World in Conflict benchmark it actually dropped behind. Still, thanks to its Fermi roots, the GTX 470 has still got the tessellation goods and this promises some future-proofing.

This card has been superseded by the likes of the GTX 560 Ti though, which means that it's not going to get replaced once stock levels do become exhausted. Worth considering while you can find it, though.

2. AMD Radeon HD 5850 (£140)

best graphics cards

The Radeon HD 5850 came out shortly after AMD's flagship DirectX 11 graphics card, the Radeon HD 5870.

As with many graphics families, this second-tier offering represented – and still represents – incredible value for money thanks to offering up the same feature set and only a slightly reduced specification from the top-of-the-range card, albeit at a much more attractive price point.

When this card cost £225, it offered great value for money. These days it's considerably cheaper than that, and has had to weather competition from both AMD and Nvidia, but it still puts it a good show in the latest games.

There are also rumours that more affordable versions of the Radeon HD 5850 are in the works, so be prepare to shop around to bag a bargain.

1. Nvidia GeForce GTX 460 1GB (£130)

best graphics cards

The 1GB version of the GTX 460 (there's also a noticeably less powerful 768MB iteration) started at a price-point that undercut its immediate Radeon-shaped competition by a fair margin, and that's only got better as the months have gone by.

The GTX 460's rejigged GF100 GPU though may sound like Nvidia has just chopped the GTX 480's chip in half, with only seven streaming multiprocessors (SMs) against the older card's fourteen, but inside, things have most definitely changed.

These SMs are the units that hold the myriad CUDA cores (previously known as shader processors), special function units (SFUs), texture mapping units (TMUs) and the polymorph engines that contain the all-important tessellation grunt.

The SMs of the GF100 chips contain a maximum of 32 shader cores, four SFUs and four TMUs. In the GTX 460 chip though Nvidia has squeezed another 16 CUDA cores into each SM and upped the SFU and TMU counts to eight per SM.

Each of these SMs has also had some CPU-like extra multi-threading goodness injected into them in the shape of an extra couple of dispatch units in each of them.

What this means is awesome midrange performance, and respectable performance at resolutions higher than 1680 x 1050. Pair a couple up for SLI kicks though, and you get a punchy setup that can rival Nvidia's own GTX 580.

These mid-range graphics card represent the sensible money for most PC gamers; combining great raw performance with a price tag that won't make you pass out.

If you're looking to power a screen with a native resolution of 1,680 x 1,050 or 1,920 x 1,080, then you really don't need to get anything more powerful than this. At least given the current slew of games.

These cards also hold an ace up their sleeve if you have an SLI or CrossFire motherboard in your rig, because they enable you to boost the performance of your machine by adding in a second card as your needs progress.

5. Nvidia GeForce GTX 550 (£128)

best graphics card

Originally designed to replace the GTS 450, the GTX 550 Ti has recently found itself being pushed out of the frame by the Radeon HD 6790 (which we're looking at next). Yes, it's a next-generation graphics card, but is that alone enough to make it relevant? Not really.

As with the Radeon HD 6790, The GTX 550 Ti suffers comparison with the slower, but more-affordable GTS 450 and the faster, and only a bit more pricey GeForce GTX 460. Indeed it's testament to the GTX 460 that it still manages to define this end of the market.

If you've got a 20-inch or 22-inch screen, then the GTX 550 Ti is briefly worth considering, because it will produce playable framerates at 1,680 x 1,050 at reasonable settings. Unfortunately, unless there's a bizarre disease that specifically targets the GTX 460 and removes it from the world, we'd recommend hunting down that older card every time.

4. AMD Radeon HD 6790 (£110)

best graphics cards

The latest addition to the graphics card market comes hot on the heels of the fastest graphics cards ever released, namely the AMD Radeon HD 6990 and the Nvidia GeForce GTX 590.

However unlike those behemoths of modern unified shader engineering, this is a card aimed squarely at the affordable end of the market. And as such, it finds itself battling for relevance against the likes of the GTX 460, the GTX 550 and even AMD's own Radeon HD 5770 at the more-affordable end of things.

Using the Barts LE core, this shares more of the inner workings of the Radeon HD 6850 and 6870 than it does the far more impressive Cayman powered 6950. That said, this is an affordable card, and as such AMD is forced to focus on budgets rather than capabilities. It shows as well, and ultimately comes up a little short in the comparisons – although it does a good job of sticking it to the GTX 550 Ti, and at a lower price.

In essence this isn't a bad card, it merely lacks the oomph to make it stand out on one side, or a really low price tag to make it stand out on the other. It's neither one nor the other. Given the spectre that is the GTX 460 still towers over it, and can be had for only £20 or so more, you're better offer forgoing a few pints and grabbing one of those instead.

3. AMD Radeon HD 6850 (£135)

best graphics cards

Launched at the same time as its slightly costlier sibling, the Radeon HD 6870, the Barts XT powered Radeon HD 6850 graphics processor failed to impress at launch due almost entirely to its misguided pricing. For reference, the card originally shipped at £160, at a time when Nvidia was cutting the price of comparably-powerful GTX 460.

The Barts XT GPU was essentially a stop gap while AMD put the finishing touches to the Cayman GPU that can be found powering the incredible Radeon HD 6950 GPU. Beyond a more power-efficient core, and a slightly reworked tessellation engine, this cards only real claim to fame is that it was the first of the second-generation of DX11 graphics cards.

The fact that it failed to comprehensively better the Radeon HD 5850 its name would suggest it was meant to replace also grated, and even though it's officially supposed to be heading for end of life status, you'd still rather pick up a 5850 to one of these.

Time has started to treat the Radeon HD 6850 a little fairer though, and a good £20-30 has been shaved off the launch price to make for a slightly more appealing pixel-pusher.

Better value cards can still be had for less, while those looking for real power should set their sights on the Radeon HD 6950. Having said that, if you can pick up the 6850 at closer to £120, then it'll give the budget-licious GTX 460 a run for its money, and is worth grabbing.

2. Nvidia GeForce GTX 560 (£200)

best graphics card

Given how the GTX 460 has come to define the budget end of the graphics card market, it was only a matter of time before Nvidia released its successor, the GTX 560 Ti. And while it would have been nice to see this card roll out £50 cheaper than this, given the technology throbbing away inside its black exterior, that would be a lot to ask.

In actual fact this card is pitched more against the GTX 470, both in terms of pricing and performance. The re-engineered Fermi core has been refined and tweaked to produce an impressive graphics processor, packing 384 CUDA cores and 64 texture units into its monolithic design.

The GTX 560 Ti may lack the vapour chamber cooling of the top-end cores, but that doesn't stop it being an incredible little overclocker. Anyone looking to get a bit more performance out of their quality graphics card has a decent amount to play with here too.

This is an impressive graphics card, and if you have a particularly unreasonable allegiance to Nvidia then you're not completely off the money. The problem is, the AMD Radeon HD 6950 has a serious trick up its sleeve, performs where it needs, and can be had for only £10 more. And when you're looking at this much cash, that's money you really should spend.

1. AMD Radeon HD 6950 (£210)

best graphics card

Every few years a graphics card is released that sums up that generation better than any other. We're talking about the likes of the 8800GT and the budget-focused Radeon X1950 Pro. Cards that transcend their immediate markets and time frames and stand up for years to come as being bang on the money.

The AMD Radeon HD 6950 defines the market. Cheaper cards look up to it for its raw power, while the top-end cards are mindful of the sheer value it offers and are rightly fearful of what can be achieved when two are cajoled together in CrossFire.

The Radeon HD 6950 isn't a subtle reworking of the first generation of DX11 graphics in the same way that Barts is, but rather a complete reworking of the inner logic of AMDs graphics chips. And its an incredible card for it.

The performance is incredible at console-breaking 1080p resolutions, and in DX11 games it punches well above its weight. If you're looking for a no-nonsense card that will last you until DX12 rolls out, and don't plan on running insanely high resolutions, this is the card for you.

Those with the stomach for it will discover that they can turn their £200 Radeon HD 6950 into a fully fledged 6970 with a BIOS flash as well. Here is a card that both AMD and Nvidia are going to be hard pushed to beat any time soon. Simply incredible.

The following five cards represent the pinnacle of modern graphics performance. These are cards that are beyond the sweet spot of what's needed in order to enjoy the latest games at reasonable resolutions.

The following cards are essentially here to fill the niches in gamers requirements that the likes of the Radeon HD 5960 cannot satisfy. Here we're talking about outputting to 27-inch and 30-inch panels that have a native resolution of 2560 x 1600. Or multiple screen displays made up of three or more 22-inch or 24-inch panels.


This end of the market is complicated somewhat by the advances made in SLI and CrossFire. These twin-graphics card pairing technologies now genuinely provide the performance improvements over single cards that you would hope for – 90-95% is often the norm.

A pair of cheaper cards in SLI can outperform the following cards too, which means the requirement of having a supporting motherboard is generally the only thing that is holding you back.

5. AMD Radeon HD 6970 (£260)

best graphics cards

Given that the AMD Radeon HD 6970 is simply a faster spin of the Radeon HD 6950 with more of everything that makes that card so great, surely this then is a fine card worthy of the money? Not quite.

The problem is, while Radeon HD 6950 is slower than this, it's only just slower. At the higher resolutions, which is all that really matters for these high-end cards, we're talking a few frames per second different at most.

In real terms you'd be hard pushed to spot such differences, which means that the extra £50 you pay for this over the cheaper card doesn't really pay off. That and the fact that the first slew of Radeon HD 6950s can be flashed to essentially turn them into 6970s conspire to make this a card that doesn't quite add up.

The fact of the matter is: if you want the kind of performance that will drive a bigger display, you're going to need to spend more than this.

4. Nvidia GeForce GTX 590 (£584)

best graphics cards

The Nvidia GeForce GTX 590 is a dual-GPU graphics card, similar in performance and guise to the Radeon HD 6990 that proceeded it into the market by roughly a month.

This means that inside that huge cooler you'll find a pair of GTX 580 cores humming away at not-quite GTX 580 speeds. In real terms that equates to a whopping 1024 CUDA cores, 96 ROPS and access to a healthy 3GB of GDDR5.

In order to fit a pair of GPUs inside a single card though, speed sacrifices have had to be made.

In the case of the GeForce GTX 590, that means dropping the core clock from the GTX 580's 772MHz down to a 607MHz. The memory speed too has been slashed, from 1.02GHz down to 853MHz.

As with the Radeon HD 6990, anyone looking for the ultimate in performance should really look at pairing up two GTX 580s, although that will cost you considerably more.

We've given the Radeon HD 6990 the slight nod over the GTX 590 simply because it does have the lead in the titles that matter, however slight that actually is.

3. AMD Radeon HD 6990 (£550)

best graphics cards

The Radeon HD 6990 is the second of two cards that utilise a pair of graphics processors to produce framerates that are out of this world. Although as you can see, this does come at a obvious downside – the pricing.

The Radeon HD 6990 utilises a new graphics processor, named Antilles, which is a slightly tweaked take on the Cayman core that can be found in the Radeon HD 6870, albeit not at the full speed of that GPU. This means you get the full 4GB of GDDR5 memory, strong tessellation performance and a stunning 3,072 streaming processors for handling your games.

Unfortunately, in order to cram two GPUs into the power footprint of a single graphics card, the core clock speed has had to be reduced from 880MHz to 830MHz. Similarly, the memory is running at 1.25GHz as opposed to the 1.375GHz of the 6970.

In truth there really isn't a lot between this and the previous card, the GTX 590 – they offer roughly the same performance and cost about the same.

If you're in the market for a dual-GPU graphics card, then your preference essentially comes down to whether you prefer AMD's drivers and support, or Nvidia's.

2. Nvidia GeForce GTX 570 (£280)

best graphics card

Value for money may seem like a strange metric to pull out of the hat at this end of the graphics market, but the GTX 570 does a decent turn at making your investment feel prudent rather than simply excessive.

Essentially a replacement for the soon to be retired GTX 480, here is a card that essentially does everything that Nvidia's last-generation top dog did, but without the problems that card suffered from when it shipped.

The cooler is quiet and more efficient, and the raw power on offer from this sub-£300 card is stunning. This is a slightly cut down version of the GTX 580, losing one Streaming Multiprocessor (or 32 CUDA cores to put it another way) and 8 ROPs.

The GTX 570's core operates at 732MHz as opposed to the GTX 580's 772MHz, while the 1,280MB of GGDR5 memory speeds along at 950MHz, as opposed to the GTX 580's 1,002MHz.

For the money, there isn't a lot out there that can touch the GTX 570 in terms of pure performance, apart from possible a pair of GTX 460s in SLI – but such a configuration does require an SLI motherboard.

1. Nvidia GeForce GTX 580 (£395)

best graphics cards

The GeForce GTX 580 is the fastest single-GPU graphics card currently available, and probably will be the only option for some time to come yet.

Created as the spiritual successor to the much-maligned GTX 480, Nvidia took the problems it had with its first DX11 graphics card and corrected them.

This means you get a full-fat core boasting 512 CUDA cores and 48 ROPS, not one that has been cut down to achieve better yields. And all running at a healthy 772MHz with a 1,002MHz memory bus for the 1,384MB of GDDR5 memory.

Not everyone needs the power of a GTX 580 – only those with serious screens to power. This is a market targeted by the twin-GPU Goliaths that are the AMD Radeon HD 6990 and Nvidia' own GeForce GTX 590.

The GTX 580 still has the nod though, because those cards have had to be throttled back to fit on a single card, while here you know nothing is being constrained. This is still the most sensible option for anyone looking for unfettered speed from a single GPU.



Updated: 15 best graphics cards in the world today

Posted: 07 Apr 2011 08:39 AM PDT

The PC is lining up for a brilliant year. It's already been highlighted as the platform of choice for for the likes of Bulletstorm, Crysis 2 and Dragon Age 2 to name but a few. And as the consoles stagnate due to their ageing technology, it's something that's only set to continue.

In order to experience such games at their best though, you're going to need to ensure you have a machine that's up to the task. And by machine we're primarily focusing on your graphics card.

It's the graphics card that does the serious work when it comes to rendering your games, and the more effects and higher resolutions you throw at it, the more is asked of that graphics card.

It's important to pick your graphics card so that it works well with your display, or displays. There's no point for instance, trying to power a 30-inch screen with the likes of a GeForce GTS 450. By the same notion, running a standard 20-inch screen with the likes of Radeon HD 6990 won't begin to tap into the cards power.

As a quick rule of thumb, whatever you spent on your screen, you're going to want to spend a similar amount to power it. Roughly.

The question is, which one of the many graphics cards out there should you actually spend your hard earned cash on? Here TechRadar highlights the top fifteen cards worth considering. We cover the notable cards from the last generation, the best all-rounders for most PC gamers, and the £550 monsters that can handle multi-screen outputs.

In this guide though we'll let you know what's hot, what's cool and what the fastest GPUs available right now and worthy of your time are.

Best of all, because we're now enjoying the second generation of DirectX 11 hardware, every card we look at here is capable of rendering the latest, funkiest DirectX 11 games.

So how does your graphics card stand in our countdown, and is it time for an upgrade? Well, there's only one way to find out…

ATI radeon hd 5970

There are a lot of terms and acronyms that get bandied around when talking about graphics cards, and not a lot of explanation to go along with them.

Before we delve into the meat of the feature let's take a minute to clear things up a little.

GPU - This is the graphics processing unit, the chip at the heart of the graphics card. Many cards use the same GPU but partner it with different components and at different clockspeeds to produce slower or faster graphics cards.

GDDR - Graphics Double Data Rate memory is the specific kind of memory that is used on graphics cards.

ROPs - The Render Output unit comes into play during the final stages in the rendering process, bringing together the data from each of the memory buffers in the graphics card's local memory. The more of them you have, the better off you are.

CUDA - The Compute Unified Device Architecture is a coding language Nvidia invented to allow parallel computing on its range of GPUs. From its 8 series upwards all its cards can use CUDA to speed up parallel processing applications, such as video encoding, in a faster way than your computer's CPU.

PhysX - Originally an accelerator chip and software layer from the small company Ageia, Nvidia bought up PhysX and has now applied it to its GPUs, again from the 8 series forward. It allows for more advanced physics simulations, such as liquid or cloth, in games that have been coded with the PhysX software included.

Crossfire and SLI - These are the relevant multi-GPU configurations from both AMD and Nvidia. Both allow multiple graphics cards to be connected together to increase the rendering performance. Historically this has been fraught with driver issues and diminishing returns for the extra cards, but as the latest cards have been released we are getting closer to doubling the performance by adding in a second card.

PCB - The Printed Circuit Board is the physical board that graphics cards (and all other micro-electronics) have their components attached to. The boards are printed with conductive pathways between the relevant components instead of using physical wires.

DirectX - Microsoft's DirectX is a collection of its own proprietary APIs (application programming interfaces) for dealing with multimedia tasks on its own operating systems. The Direct3D part is specifically to do with 3D graphics and utilises hardware acceleration if there is a GPU in place to take advantage of it.

Tesselation - This is one of the key buzzwords to come from Microsoft's latest graphical API, DirectX 11. Essentially it is designed to add extra geometry to a simple polygon using displacement maps to tell the GPU where to raise and lower parts of the polygon as the graphics card computes the data. The idea being to add geometry to objects in a game world without significantly impairing performance and it is set to become a key battleground in the graphics war in the coming years.

The first generation of DirectX 11 graphics cards boasted some notable GPUs. Here's are low-down of the cards that still manage to be relevant even after the second slew of cards settles in:

5. Nvidia GeForce GTS 450 (£85)

Best graphics cards

If 1680 x 1050 is the mass-market gaming resolution of choice, then the GTS 450 is opium for the masses.

This tiny powerhouse (well, it's still dual-width, but pleasingly short) is capable of feats beyond its £80-£90 price tag. What's more, in SLI, you'll see massive performance gains, making the dual-card upgrade path a realistic and impressive option for budget systems.

The basic GeForce GTS 450 is, architecturally, about half of a GeForce 460 with a higher clockspeed and a narrower memory bus.

However, the GTS 450 has the advantage over the GTX 460 of being smaller and requiring less power, which makes it a strong candidate for that SLI set-up

It is, however, now pitched directly up against the HD 5750 in pricing terms thanks to the on-going Nvidia/AMD graphics card price wars. And that is a card the GTS 450 happily beats into submission in any benchmark you throw at it.

4. AMD Radeon HD 5770 (£100)

best graphics cards

For budget-conscious gamers, the HD 5770 should be a serious consideration. Have a scout around the online retailers, and you'll see that examples can be had for less than £100 now.

Offering competent performance at the mainstream 22-inch resolution of 1680 x 1050, it also comes with the promise of cool-running, quiet operation – a trademark of AMD's last-gen design philosophy.

However, try to crank the shinier graphical elements – such as Anti-Aliasing and Anisotropic Filtering – too high, and the card starts to run out of grunt.

AMD's EyeFinity technology, which enables multi-screen scaling, is a very real option with the 5770, though we wouldn't recommend the 5770 for multi-screen gaming; it just doesn't have the throughput for gaming at huge resolutions.

But the really interesting thing about the HD 5770 is what its price represents. At these low prices, our thoughts turn to CrossFire setups. For under £200, you can net yourself a twin-card setup that offers kick-ass performance at mid-range resolutions.

If you're content with that 22-inch monitor and want zingy performance on a budget, this CF setup is probably the cheapest way to achieve it... Oh, and did we mention the 5770 is DX11 capable? Yum.

3. Nvidia GeForce GTX 470 (£160)

best graphics card

Not so hot on the heels of Nvidia's first DX11 graphics cards came the GeForce GTX 470, a cut-down version of the GF100 GPU the green company is rightfully proud of.

Given the larger pricetag of its big brother, the GTX 480, this represents the most affordable high-end Fermi card of the first generation.

Like the rest of the Fermi range, the 470 has seen some nifty price-cuts, which means it can now be had for £160. This makes the cheapest 470s at just £30 more expensive than the GTX 460 1GB, the new midrange king. That makes it a pretty compelling prospect right now.

In addition, at the native 22-inch resolution of 1680 x 1050, this card is a fair way ahead of the HD 5870. When things get cranked up though, it starts to lose its competitive edge against AMD's upper-midrange peer.

Indeed, in our World in Conflict benchmark it actually dropped behind. Still, thanks to its Fermi roots, the GTX 470 has still got the tessellation goods and this promises some future-proofing.

This card has been superseded by the likes of the GTX 560 Ti though, which means that it's not going to get replaced once stock levels do become exhausted. Worth considering while you can find it, though.

2. AMD Radeon HD 5850 (£140)

best graphics cards

The Radeon HD 5850 came out shortly after AMD's flagship DirectX 11 graphics card, the Radeon HD 5870.

As with many graphics families, this second-tier offering represented – and still represents – incredible value for money thanks to offering up the same feature set and only a slightly reduced specification from the top-of-the-range card, albeit at a much more attractive price point.

When this card cost £225, it offered great value for money. These days it's considerably cheaper than that, and has had to weather competition from both AMD and Nvidia, but it still puts it a good show in the latest games.

There are also rumours that more affordable versions of the Radeon HD 5850 are in the works, so be prepare to shop around to bag a bargain.

1. Nvidia GeForce GTX 460 1GB (£130)

best graphics cards

The 1GB version of the GTX 460 (there's also a noticeably less powerful 768MB iteration) started at a price-point that undercut its immediate Radeon-shaped competition by a fair margin, and that's only got better as the months have gone by.

The GTX 460's rejigged GF100 GPU though may sound like Nvidia has just chopped the GTX 480's chip in half, with only seven streaming multiprocessors (SMs) against the older card's fourteen, but inside, things have most definitely changed.

These SMs are the units that hold the myriad CUDA cores (previously known as shader processors), special function units (SFUs), texture mapping units (TMUs) and the polymorph engines that contain the all-important tessellation grunt.

The SMs of the GF100 chips contain a maximum of 32 shader cores, four SFUs and four TMUs. In the GTX 460 chip though Nvidia has squeezed another 16 CUDA cores into each SM and upped the SFU and TMU counts to eight per SM.

Each of these SMs has also had some CPU-like extra multi-threading goodness injected into them in the shape of an extra couple of dispatch units in each of them.

What this means is awesome midrange performance, and respectable performance at resolutions higher than 1680 x 1050. Pair a couple up for SLI kicks though, and you get a punchy setup that can rival Nvidia's own GTX 580.

These mid-range graphics card represent the sensible money for most PC gamers; combining great raw performance with a price tag that won't make you pass out.

If you're looking to power a screen with a native resolution of 1,680 x 1,050 or 1,920 x 1,080, then you really don't need to get anything more powerful than this. At least given the current slew of games.

These cards also hold an ace up their sleeve if you have an SLI or CrossFire motherboard in your rig, because they enable you to boost the performance of your machine by adding in a second card as your needs progress.

5. Nvidia GeForce GTX 550 (£128)

best graphics card

Originally designed to replace the GTS 450, the GTX 550 Ti has recently found itself being pushed out of the frame by the Radeon HD 6790 (which we're looking at next). Yes, it's a next-generation graphics card, but is that alone enough to make it relevant? Not really.

As with the Radeon HD 6790, The GTX 550 Ti suffers comparison with the slower, but more-affordable GTS 450 and the faster, and only a bit more pricey GeForce GTX 460. Indeed it's testament to the GTX 460 that it still manages to define this end of the market.

If you've got a 20-inch or 22-inch screen, then the GTX 550 Ti is briefly worth considering, because it will produce playable framerates at 1,680 x 1,050 at reasonable settings. Unfortunately, unless there's a bizarre disease that specifically targets the GTX 460 and removes it from the world, we'd recommend hunting down that older card every time.

4. AMD Radeon HD 6790 (£110)

best graphics cards

The latest addition to the graphics card market comes hot on the heels of the fastest graphics cards ever released, namely the AMD Radeon HD 6990 and the Nvidia GeForce GTX 590.

However unlike those behemoths of modern unified shader engineering, this is a card aimed squarely at the affordable end of the market. And as such, it finds itself battling for relevance against the likes of the GTX 460, the GTX 550 and even AMD's own Radeon HD 5770 at the more-affordable end of things.

Using the Barts LE core, this shares more of the inner workings of the Radeon HD 6850 and 6870 than it does the far more impressive Cayman powered 6950. That said, this is an affordable card, and as such AMD is forced to focus on budgets rather than capabilities. It shows as well, and ultimately comes up a little short in the comparisons – although it does a good job of sticking it to the GTX 550 Ti, and at a lower price.

In essence this isn't a bad card, it merely lacks the oomph to make it stand out on one side, or a really low price tag to make it stand out on the other. It's neither one nor the other. Given the spectre that is the GTX 460 still towers over it, and can be had for only £20 or so more, you're better offer forgoing a few pints and grabbing one of those instead.

3. AMD Radeon HD 6850 (£135)

best graphics cards

Launched at the same time as its slightly costlier sibling, the Radeon HD 6870, the Barts XT powered Radeon HD 6850 graphics processor failed to impress at launch due almost entirely to its misguided pricing. For reference, the card originally shipped at £160, at a time when Nvidia was cutting the price of comparably-powerful GTX 460.

The Barts XT GPU was essentially a stop gap while AMD put the finishing touches to the Cayman GPU that can be found powering the incredible Radeon HD 6950 GPU. Beyond a more power-efficient core, and a slightly reworked tessellation engine, this cards only real claim to fame is that it was the first of the second-generation of DX11 graphics cards.

The fact that it failed to comprehensively better the Radeon HD 5850 its name would suggest it was meant to replace also grated, and even though it's officially supposed to be heading for end of life status, you'd still rather pick up a 5850 to one of these.

Time has started to treat the Radeon HD 6850 a little fairer though, and a good £20-30 has been shaved off the launch price to make for a slightly more appealing pixel-pusher.

Better value cards can still be had for less, while those looking for real power should set their sights on the Radeon HD 6950. Having said that, if you can pick up the 6850 at closer to £120, then it'll give the budget-licious GTX 460 a run for its money, and is worth grabbing.

2. Nvidia GeForce GTX 560 (£200)

best graphics card

Given how the GTX 460 has come to define the budget end of the graphics card market, it was only a matter of time before Nvidia released its successor, the GTX 560 Ti. And while it would have been nice to see this card roll out £50 cheaper than this, given the technology throbbing away inside its black exterior, that would be a lot to ask.

In actual fact this card is pitched more against the GTX 470, both in terms of pricing and performance. The re-engineered Fermi core has been refined and tweaked to produce an impressive graphics processor, packing 384 CUDA cores and 64 texture units into its monolithic design.

The GTX 560 Ti may lack the vapour chamber cooling of the top-end cores, but that doesn't stop it being an incredible little overclocker. Anyone looking to get a bit more performance out of their quality graphics card has a decent amount to play with here too.

This is an impressive graphics card, and if you have a particularly unreasonable allegiance to Nvidia then you're not completely off the money. The problem is, the AMD Radeon HD 6950 has a serious trick up its sleeve, performs where it needs, and can be had for only £10 more. And when you're looking at this much cash, that's money you really should spend.

1. AMD Radeon HD 6950 (£210)

best graphics card

Every few years a graphics card is released that sums up that generation better than any other. We're talking about the likes of the 8800GT and the budget-focused Radeon X1950 Pro. Cards that transcend their immediate markets and time frames and stand up for years to come as being bang on the money.

The AMD Radeon HD 6950 defines the market. Cheaper cards look up to it for its raw power, while the top-end cards are mindful of the sheer value it offers and are rightly fearful of what can be achieved when two are cajoled together in CrossFire.

The Radeon HD 6950 isn't a subtle reworking of the first generation of DX11 graphics in the same way that Barts is, but rather a complete reworking of the inner logic of AMDs graphics chips. And its an incredible card for it.

The performance is incredible at console-breaking 1080p resolutions, and in DX11 games it punches well above its weight. If you're looking for a no-nonsense card that will last you until DX12 rolls out, and don't plan on running insanely high resolutions, this is the card for you.

Those with the stomach for it will discover that they can turn their £200 Radeon HD 6950 into a fully fledged 6970 with a BIOS flash as well. Here is a card that both AMD and Nvidia are going to be hard pushed to beat any time soon. Simply incredible.

The following five cards represent the pinnacle of modern graphics performance. These are cards that are beyond the sweet spot of what's needed in order to enjoy the latest games at reasonable resolutions.

The following cards are essentially here to fill the niches in gamers requirements that the likes of the Radeon HD 5960 cannot satisfy. Here we're talking about outputting to 27-inch and 30-inch panels that have a native resolution of 2560 x 1600. Or multiple screen displays made up of three or more 22-inch or 24-inch panels.


This end of the market is complicated somewhat by the advances made in SLI and CrossFire. These twin-graphics card pairing technologies now genuinely provide the performance improvements over single cards that you would hope for – 90-95% is often the norm.

A pair of cheaper cards in SLI can outperform the following cards too, which means the requirement of having a supporting motherboard is generally the only thing that is holding you back.

5. AMD Radeon HD 6970 (£260)

best graphics cards

Given that the AMD Radeon HD 6970 is simply a faster spin of the Radeon HD 6950 with more of everything that makes that card so great, surely this then is a fine card worthy of the money? Not quite.

The problem is, while Radeon HD 6950 is slower than this, it's only just slower. At the higher resolutions, which is all that really matters for these high-end cards, we're talking a few frames per second different at most.

In real terms you'd be hard pushed to spot such differences, which means that the extra £50 you pay for this over the cheaper card doesn't really pay off. That and the fact that the first slew of Radeon HD 6950s can be flashed to essentially turn them into 6970s conspire to make this a card that doesn't quite add up.

The fact of the matter is: if you want the kind of performance that will drive a bigger display, you're going to need to spend more than this.

4. Nvidia GeForce GTX 590 (£584)

best graphics cards

The Nvidia GeForce GTX 590 is a dual-GPU graphics card, similar in performance and guise to the Radeon HD 6990 that proceeded it into the market by roughly a month.

This means that inside that huge cooler you'll find a pair of GTX 580 cores humming away at not-quite GTX 580 speeds. In real terms that equates to a whopping 1024 CUDA cores, 96 ROPS and access to a healthy 3GB of GDDR5.

In order to fit a pair of GPUs inside a single card though, speed sacrifices have had to be made.

In the case of the GeForce GTX 590, that means dropping the core clock from the GTX 580's 772MHz down to a 607MHz. The memory speed too has been slashed, from 1.02GHz down to 853MHz.

We've given the Radeon HD 6990 the slight nod over the GTX 590 simply because it does have the lead in the titles that matter, however slight that actually is.

CUDA - The Compute Unified Device Architecture is a coding language Nvidia invented to allow parallel computing on its range of GPUs. From its 8 series upwards all its cards can use CUDA to speed up parallel processing applications, such as video encoding, in a faster way than your computer's CPU.

PhysX - Originally an accelerator chip and software layer from the small company Ageia, Nvidia bought up PhysX and has now applied it to its GPUs, again from the 8 series forward. It allows for more advanced physics simulations, such as liquid or cloth, in games that have been coded with the PhysX software included.

Crossfire and SLI - These are the relevant multi-GPU configurations from both AMD and Nvidia. Both allow multiple graphics cards to be connected together to increase the rendering performance. Historically this has been fraught with driver issues and diminishing returns for the extra cards, but as the latest cards have been released we are getting closer to doubling the performance by adding in a second card.

PCB - The Printed Circuit Board is the physical board that graphics cards (and all other micro-electronics) have their components attached to. The boards are printed with conductive pathways between the relevant components instead of using physical wires.

DirectX - Microsoft's DirectX is a collection of its own proprietary APIs (application programming interfaces) for dealing with multimedia tasks on its own operating systems. The Direct3D part is specifically to do with 3D graphics and utilises hardware acceleration if there is a GPU in place to take advantage of it.

Tesselation - This is one of the key buzzwords to come from Microsoft's latest graphical API, DirectX 11. Essentially it is designed to add extra geometry to a simple polygon using displacement maps to tell the GPU where to raise and lower parts of the polygon as the graphics card computes the data. The idea being to add geometry to objects in a game world without significantly impairing performance and it is set to become a key battleground in the graphics war in the coming years.

The first generation of DirectX 11 graphics cards boasted some notable GPUs. Here's are low-down of the cards that still manage to be relevant even after the second slew of cards settles in:

5. Nvidia GeForce GTS 450 (£85)

Best graphics cards

If 1680 x 1050 is the mass-market gaming resolution of choice, then the GTS 450 is opium for the masses.

This tiny powerhouse (well, it's still dual-width, but pleasingly short) is capable of feats beyond its £80-£90 price tag. What's more, in SLI, you'll see massive performance gains, making the dual-card upgrade path a realistic and impressive option for budget systems.

The basic GeForce GTS 450 is, architecturally, about half of a GeForce 460 with a higher clockspeed and a narrower memory bus.

However, the GTS 450 has the advantage over the GTX 460 of being smaller and requiring less power, which makes it a strong candidate for that SLI set-up

It is, however, now pitched directly up against the HD 5750 in pricing terms thanks to the on-going Nvidia/AMD graphics card price wars. And that is a card the GTS 450 happily beats into submission in any benchmark you throw at it.

4. AMD Radeon HD 5770 (£100)

best graphics cards

For budget-conscious gamers, the HD 5770 should be a serious consideration. Have a scout around the online retailers, and you'll see that examples can be had for less than £100 now.

Offering competent performance at the mainstream 22-inch resolution of 1680 x 1050, it also comes with the promise of cool-running, quiet operation – a trademark of AMD's last-gen design philosophy.

However, try to crank the shinier graphical elements – such as Anti-Aliasing and Anisotropic Filtering – too high, and the card starts to run out of grunt.

AMD's EyeFinity technology, which enables multi-screen scaling, is a very real option with the 5770, though we wouldn't recommend the 5770 for multi-screen gaming; it just doesn't have the throughput for gaming at huge resolutions.

But the really interesting thing about the HD 5770 is what its price represents. At these low prices, our thoughts turn to CrossFire setups. For under £200, you can net yourself a twin-card setup that offers kick-ass performance at mid-range resolutions.

If you're content with that 22-inch monitor and want zingy performance on a budget, this CF setup is probably the cheapest way to achieve it... Oh, and did we mention the 5770 is DX11 capable? Yum.

3. Nvidia GeForce GTX 470 (£160)

best graphics card

Not so hot on the heels of Nvidia's first DX11 graphics cards came the GeForce GTX 470, a cut-down version of the GF100 GPU the green company is rightfully proud of.

Given the larger pricetag of its big brother, the GTX 480, this represents the most affordable high-end Fermi card of the first generation.

Like the rest of the Fermi range, the 470 has seen some nifty price-cuts, which means it can now be had for £160. This makes the cheapest 470s at just £30 more expensive than the GTX 460 1GB, the new midrange king. That makes it a pretty compelling prospect right now.

In addition, at the native 22-inch resolution of 1680 x 1050, this card is a fair way ahead of the HD 5870. When things get cranked up though, it starts to lose its competitive edge against AMD's upper-midrange peer.

Indeed, in our World in Conflict benchmark it actually dropped behind. Still, thanks to its Fermi roots, the GTX 470 has still got the tessellation goods and this promises some future-proofing.

This card has been superseded by the likes of the GTX 560 Ti though, which means that it's not going to get replaced once stock levels do become exhausted. Worth considering while you can find it, though.

2. AMD Radeon HD 5850 (£140)

best graphics cards

The Radeon HD 5850 came out shortly after AMD's flagship DirectX 11 graphics card, the Radeon HD 5870.

As with many graphics families, this second-tier offering represented – and still represents – incredible value for money thanks to offering up the same feature set and only a slightly reduced specification from the top-of-the-range card, albeit at a much more attractive price point.

When this card cost £225, it offered great value for money. These days it's considerably cheaper than that, and has had to weather competition from both AMD and Nvidia, but it still puts it a good show in the latest games.

There are also rumours that more affordable versions of the Radeon HD 5850 are in the works, so be prepare to shop around to bag a bargain.

1. Nvidia GeForce GTX 460 1GB (£130)

best graphics cards

The 1GB version of the GTX 460 (there's also a noticeably less powerful 768MB iteration) started at a price-point that undercut its immediate Radeon-shaped competition by a fair margin, and that's only got better as the months have gone by.

The GTX 460's rejigged GF100 GPU though may sound like Nvidia has just chopped the GTX 480's chip in half, with only seven streaming multiprocessors (SMs) against the older card's fourteen, but inside, things have most definitely changed.

These SMs are the units that hold the myriad CUDA cores (previously known as shader processors), special function units (SFUs), texture mapping units (TMUs) and the polymorph engines that contain the all-important tessellation grunt.

The SMs of the GF100 chips contain a maximum of 32 shader cores, four SFUs and four TMUs. In the GTX 460 chip though Nvidia has squeezed another 16 CUDA cores into each SM and upped the SFU and TMU counts to eight per SM.

Each of these SMs has also had some CPU-like extra multi-threading goodness injected into them in the shape of an extra couple of dispatch units in each of them.

What this means is awesome midrange performance, and respectable performance at resolutions higher than 1680 x 1050. Pair a couple up for SLI kicks though, and you get a punchy setup that can rival Nvidia's own GTX 580.

These mid-range graphics card represent the sensible money for most PC gamers; combining great raw performance with a price tag that won't make you pass out.

If you're looking to power a screen with a native resolution of 1,680 x 1,050 or 1,920 x 1,080, then you really don't need to get anything more powerful than this. At least given the current slew of games.

These cards also hold an ace up their sleeve if you have an SLI or CrossFire motherboard in your rig, because they enable you to boost the performance of your machine by adding in a second card as your needs progress.

5. Nvidia GeForce GTX 550 (£128)

best graphics card

Originally designed to replace the GTS 450, the GTX 550 Ti has recently found itself being pushed out of the frame by the Radeon HD 6790 (which we're looking at next). Yes, it's a next-generation graphics card, but is that alone enough to make it relevant? Not really.

As with the Radeon HD 6790, The GTX 550 Ti suffers comparison with the slower, but more-affordable GTS 450 and the faster, and only a bit more pricey GeForce GTX 460. Indeed it's testament to the GTX 460 that it still manages to define this end of the market.

If you've got a 20-inch or 22-inch screen, then the GTX 550 Ti is briefly worth considering, because it will produce playable framerates at 1,680 x 1,050 at reasonable settings. Unfortunately, unless there's a bizarre disease that specifically targets the GTX 460 and removes it from the world, we'd recommend hunting down that older card every time.

4. AMD Radeon HD 6790 (£110)

best graphics cards

The latest addition to the graphics card market comes hot on the heels of the fastest graphics cards ever released, namely the AMD Radeon HD 6990 and the Nvidia GeForce GTX 590.

However unlike those behemoths of modern unified shader engineering, this is a card aimed squarely at the affordable end of the market. And as such, it finds itself battling for relevance against the likes of the GTX 460, the GTX 550 and even AMD's own Radeon HD 5770 at the more-affordable end of things.

Using the Barts LE core, this shares more of the inner workings of the Radeon HD 6850 and 6870 than it does the far more impressive Cayman powered 6950. That said, this is an affordable card, and as such AMD is forced to focus on budgets rather than capabilities. It shows as well, and ultimately comes up a little short in the comparisons – although it does a good job of sticking it to the GTX 550 Ti, and at a lower price.

In essence this isn't a bad card, it merely lacks the oomph to make it stand out on one side, or a really low price tag to make it stand out on the other. It's neither one nor the other. Given the spectre that is the GTX 460 still towers over it, and can be had for only £20 or so more, you're better offer forgoing a few pints and grabbing one of those instead.

3. AMD Radeon HD 6850 (£135)

best graphics cards

Launched at the same time as its slightly costlier sibling, the Radeon HD 6870, the Barts XT powered Radeon HD 6850 graphics processor failed to impress at launch due almost entirely to its misguided pricing. For reference, the card originally shipped at £160, at a time when Nvidia was cutting the price of comparably-powerful GTX 460.

The Barts XT GPU was essentially a stop gap while AMD put the finishing touches to the Cayman GPU that can be found powering the incredible Radeon HD 6950 GPU. Beyond a more power-efficient core, and a slightly reworked tessellation engine, this cards only real claim to fame is that it was the first of the second-generation of DX11 graphics cards.

The fact that it failed to comprehensively better the Radeon HD 5850 its name would suggest it was meant to replace also grated, and even though it's officially supposed to be heading for end of life status, you'd still rather pick up a 5850 to one of these.

Time has started to treat the Radeon HD 6850 a little fairer though, and a good £20-30 has been shaved off the launch price to make for a slightly more appealing pixel-pusher.

Better value cards can still be had for less, while those looking for real power should set their sights on the Radeon HD 6950. Having said that, if you can pick up the 6850 at closer to £120, then it'll give the budget-licious GTX 460 a run for its money, and is worth grabbing.

2. Nvidia GeForce GTX 560 (£200)

best graphics card

Given how the GTX 460 has come to define the budget end of the graphics card market, it was only a matter of time before Nvidia released its successor, the GTX 560 Ti. And while it would have been nice to see this card roll out £50 cheaper than this, given the technology throbbing away inside its black exterior, that would be a lot to ask.

In actual fact this card is pitched more against the GTX 470, both in terms of pricing and performance. The re-engineered Fermi core has been refined and tweaked to produce an impressive graphics processor, packing 384 CUDA cores and 64 texture units into its monolithic design.

The GTX 560 Ti may lack the vapour chamber cooling of the top-end cores, but that doesn't stop it being an incredible little overclocker. Anyone looking to get a bit more performance out of their quality graphics card has a decent amount to play with here too.

This is an impressive graphics card, and if you have a particularly unreasonable allegiance to Nvidia then you're not completely off the money. The problem is, the AMD Radeon HD 6950 has a serious trick up its sleeve, performs where it needs, and can be had for only £10 more. And when you're looking at this much cash, that's money you really should spend.

1. AMD Radeon HD 6950 (£210)

best graphics card

Every few years a graphics card is released that sums up that generation better than any other. We're talking about the likes of the 8800GT and the budget-focused Radeon X1950 Pro. Cards that transcend their immediate markets and time frames and stand up for years to come as being bang on the money.

The AMD Radeon HD 6950 defines the market. Cheaper cards look up to it for its raw power, while the top-end cards are mindful of the sheer value it offers and are rightly fearful of what can be achieved when two are cajoled together in CrossFire.

The Radeon HD 6950 isn't a subtle reworking of the first generation of DX11 graphics in the same way that Barts is, but rather a complete reworking of the inner logic of AMDs graphics chips. And its an incredible card for it.

The performance is incredible at console-breaking 1080p resolutions, and in DX11 games it punches well above its weight. If you're looking for a no-nonsense card that will last you until DX12 rolls out, and don't plan on running insanely high resolutions, this is the card for you.

Those with the stomach for it will discover that they can turn their £200 Radeon HD 6950 into a fully fledged 6970 with a BIOS flash as well. Here is a card that both AMD and Nvidia are going to be hard pushed to beat any time soon. Simply incredible.

The following five cards represent the pinnacle of modern graphics performance. These are cards that are beyond the sweet spot of what's needed in order to enjoy the latest games at reasonable resolutions.

The following cards are essentially here to fill the niches in gamers requirements that the likes of the Radeon HD 5960 cannot satisfy. Here we're talking about outputting to 27-inch and 30-inch panels that have a native resolution of 2560 x 1600. Or multiple screen displays made up of three or more 22-inch or 24-inch panels.


This end of the market is complicated somewhat by the advances made in SLI and CrossFire. These twin-graphics card pairing technologies now genuinely provide the performance improvements over single cards that you would hope for – 90-95% is often the norm.

A pair of cheaper cards in SLI can outperform the following cards too, which means the requirement of having a supporting motherboard is generally the only thing that is holding you back.

5. AMD Radeon HD 6970 (£260)

best graphics cards

Given that the AMD Radeon HD 6970 is simply a faster spin of the Radeon HD 6950 with more of everything that makes that card so great, surely this then is a fine card worthy of the money? Not quite.

The problem is, while Radeon HD 6950 is slower than this, it's only just slower. At the higher resolutions, which is all that really matters for these high-end cards, we're talking a few frames per second different at most.

In real terms you'd be hard pushed to spot such differences, which means that the extra £50 you pay for this over the cheaper card doesn't really pay off. That and the fact that the first slew of Radeon HD 6950s can be flashed to essentially turn them into 6970s conspire to make this a card that doesn't quite add up.

The fact of the matter is: if you want the kind of performance that will drive a bigger display, you're going to need to spend more than this.

4. Nvidia GeForce GTX 590 (£584)

best graphics cards

The Nvidia GeForce GTX 590 is a dual-GPU graphics card, similar in performance and guise to the Radeon HD 6990 that proceeded it into the market by roughly a month.

This means that inside that huge cooler you'll find a pair of GTX 580 cores humming away at not-quite GTX 580 speeds. In real terms that equates to a whopping 1024 CUDA cores, 96 ROPS and access to a healthy 3GB of GDDR5.

In order to fit a pair of GPUs inside a single card though, speed sacrifices have had to be made.

In the case of the GeForce GTX 590, that means dropping the core clock from the GTX 580's 772MHz down to a 607MHz. The memory speed too has been slashed, from 1.02GHz down to 853MHz.

As with the Radeon HD 6990, anyone looking for the ultimate in performance should really look at pairing up two GTX 580s, although that will cost you considerably more.

We've given the Radeon HD 6990 the slight nod over the GTX 590 simply because it does have the lead in the titles that matter, however slight that actually is.

3. AMD Radeon HD 6990 (£550)

best graphics cards

The Radeon HD 6990 is the second of two cards that utilise a pair of graphics processors to produce framerates that are out of this world. Although as you can see, this does come at a obvious downside – the pricing.

The Radeon HD 6990 utilises a new graphics processor, named Antilles, which is a slightly tweaked take on the Cayman core that can be found in the Radeon HD 6870, albeit not at the full speed of that GPU. This means you get the full 4GB of GDDR5 memory, strong tessellation performance and a stunning 3,072 streaming processors for handling your games.

Unfortunately, in order to cram two GPUs into the power footprint of a single graphics card, the core clock speed has had to be reduced from 880MHz to 830MHz. Similarly, the memory is running at 1.25GHz as opposed to the 1.375GHz of the 6970.

In truth there really isn't a lot between this and the previous card, the GTX 590 – they offer roughly the same performance and cost about the same.

If you're in the market for a dual-GPU graphics card, then your preference essentially comes down to whether you prefer AMD's drivers and support, or Nvidia's.

2. Nvidia GeForce GTX 570 (£280)

best graphics card

Value for money may seem like a strange metric to pull out of the hat at this end of the graphics market, but the GTX 570 does a decent turn at making your investment feel prudent rather than simply excessive.

Essentially a replacement for the soon to be retired GTX 480, here is a card that essentially does everything that Nvidia's last-generation top dog did, but without the problems that card suffered from when it shipped.

The cooler is quiet and more efficient, and the raw power on offer from this sub-£300 card is stunning. This is a slightly cut down version of the GTX 580, losing one Streaming Multiprocessor (or 32 CUDA cores to put it another way) and 8 ROPs.

The GTX 570's core operates at 732MHz as opposed to the GTX 580's 772MHz, while the 1,280MB of GGDR5 memory speeds along at 950MHz, as opposed to the GTX 580's 1,002MHz.

For the money, there isn't a lot out there that can touch the GTX 570 in terms of pure performance, apart from possible a pair of GTX 460s in SLI – but such a configuration does require an SLI motherboard.

1. Nvidia GeForce GTX 580 (£395)

best graphics cards

The GeForce GTX 580 is the fastest single-GPU graphics card currently available, and probably will be the only option for some time to come yet.

Created as the spiritual successor to the much-maligned GTX 480, Nvidia took the problems it had with its first DX11 graphics card and corrected them.

This means you get a full-fat core boasting 512 CUDA cores and 48 ROPS, not one that has been cut down to achieve better yields. And all running at a healthy 772MHz with a 1,002MHz memory bus for the 1,384MB of GDDR5 memory.

Not everyone needs the power of a GTX 580 – only those with serious screens to power. This is a market targeted by the twin-GPU Goliaths that are the AMD Radeon HD 6990 and Nvidia' own GeForce GTX 590.

The GTX 580 still has the nod though, because those cards have had to be throttled back to fit on a single card, while here you know nothing is being constrained. This is still the most sensible option for anyone looking for unfettered speed from a single GPU.



Updated: 15 best graphics cards in the world today

Posted: 07 Apr 2011 08:39 AM PDT

The PC is lining up for a brilliant year. It's already been highlighted as the platform of choice for for the likes of Bulletstorm, Crysis 2 and Dragon Age 2 to name but a few. And as the consoles stagnate due to their ageing technology, it's something that's only set to continue.

In order to experience such games at their best though, you're going to need to ensure you have a machine that's up to the task. And by machine we're primarily focusing on your graphics card.

It's the graphics card that does the serious work when it comes to rendering your games, and the more effects and higher resolutions you throw at it, the more is asked of that graphics card.

It's important to pick your graphics card so that it works well with your display, or displays. There's no point for instance, trying to power a 30-inch screen with the likes of a GeForce GTS 450. By the same notion, running a standard 20-inch screen with the likes of Radeon HD 6990 won't begin to tap into the cards power.

As a quick rule of thumb, whatever you spent on your screen, you're going to want to spend a similar amount to power it. Roughly.

The question is, which one of the many graphics cards out there should you actually spend your hard earned cash on? Here TechRadar highlights the top fifteen cards worth considering. We cover the notable cards from the last generation, the best all-rounders for most PC gamers, and the £550 monsters that can handle multi-screen outputs.

In this guide though we'll let you know what's hot, what's cool and what the fastest GPUs available right now and worthy of your time are.

Best of all, because we're now enjoying the second generation of DirectX 11 hardware, every card we look at here is capable of rendering the latest, funkiest DirectX 11 games.

So how does your graphics card stand in our countdown, and is it time for an upgrade? Well, there's only one way to find out…

ATI radeon hd 5970

There are a lot of terms and acronyms that get bandied around when talking about graphics cards, and not a lot of explanation to go along with them.

Before we delve into the meat of the feature let's take a minute to clear things up a little.

GPU - This is the graphics processing unit, the chip at the heart of the graphics card. Many cards use the same GPU but partner it with different components and at different clockspeeds to produce slower or faster graphics cards.

GDDR - Graphics Double Data Rate memory is the specific kind of memory that is used on graphics cards.

ROPs - The Render Output unit comes into play during the final stages in the rendering process, bringing together the data from each of the memory buffers in the graphics card's local memory. The more of them you have, the better off you are.

CUDA - The Compute Unified Device Architecture is a coding language Nvidia invented to allow parallel computing on its range of GPUs. From its 8 series upwards all its cards can use CUDA to speed up parallel processing applications, such as video encoding, in a faster way than your computer's CPU.

It allows for more advanced physics simulations, such as liquid or cloth, in games that have been coded with the PhysX software included.

Crossfire and SLI - These are the relevant multi-GPU configurations from both AMD and Nvidia. Both allow multiple graphics cards to be connected together to increase the rendering performance. Historically this has been fraught with driver issues and diminishing returns for the extra cards, but as the latest cards have been released we are getting closer to doubling the performance by adding in a second card.

best graphics cards

For budget-conscious gamers, the HD 5770 should be a serious consideration. Have a scout around the online retailers, and you'll see that examples can be had for less than £100 now.

Offering competent performance at the mainstream 22-inch resolution of 1680 x 1050, it also comes with the promise of cool-running, quiet operation – a trademark of AMD's last-gen design philosophy.

If you're content with that 22-inch monitor and want zingy performance on a budget, this CF setup is probably the cheapest way to achieve it... Oh, and did we mention the 5770 is DX11 capable? Yum.

3. Nvidia GeForce GTX 470 (£160)

Each of these SMs has also had some CPU-like extra multi-threading goodness injected into them in the shape of an extra couple of dispatch units in each of them.

What this means is awesome midrange performance, and respectable performance at resolutions higher than 1680 x 1050. Pair a couple up for SLI kicks though, and you get a punchy setup that can rival Nvidia's own GTX 580.

These mid-range graphics card represent the sensible money for most PC gamers; combining great raw performance with a price tag that won't make you pass out.

If you're looking to power a screen with a native resolution of 1,680 x 1,050 or 1,920 x 1,080, then you really don't need to get anything more powerful than this. At least given the current slew of games.

These cards also hold an ace up their sleeve if you have an SLI or CrossFire motherboard in your rig, because they enable you to boost the performance of your machine by adding in a second card as your needs progress.

5. Nvidia GeForce GTX 550 (£128)

best graphics card

Originally designed to replace the GTS 450, the GTX 550 Ti has recently found itself being pushed out of the frame by the Radeon HD 6790 (which we're looking at next). Yes, it's a next-generation graphics card, but is that alone enough to make it relevant? Not really.

As with the Radeon HD 6790, The GTX 550 Ti suffers comparison with the slower, but more-affordable GTS 450 and the faster, and only a bit more pricey GeForce GTX 460. Indeed it's testament to the GTX 460 that it still manages to define this end of the market.

If you've got a 20-inch or 22-inch screen, then the GTX 550 Ti is briefly worth considering, because it will produce playable framerates at 1,680 x 1,050 at reasonable settings. Unfortunately, unless there's a bizarre disease that specifically targets the GTX 460 and removes it from the world, we'd recommend hunting down that older card every time.

4. AMD Radeon HD 6790 (£110)

best graphics cards

The latest addition to the graphics card market comes hot on the heels of the fastest graphics cards ever released, namely the AMD Radeon HD 6990 and the Nvidia GeForce GTX 590.

However unlike those behemoths of modern unified shader engineering, this is a card aimed squarely at the affordable end of the market. And as such, it finds itself battling for relevance against the likes of the GTX 460, the GTX 550 and even AMD's own Radeon HD 5770 at the more-affordable end of things.

Using the Barts LE core, this shares more of the inner workings of the Radeon HD 6850 and 6870 than it does the far more impressive Cayman powered 6950. That said, this is an affordable card, and as such AMD is forced to focus on budgets rather than capabilities. It shows as well, and ultimately comes up a little short in the comparisons – although it does a good job of sticking it to the GTX 550 Ti, and at a lower price.

In essence this isn't a bad card, it merely lacks the oomph to make it stand out on one side, or a really low price tag to make it stand out on the other. It's neither one nor the other. Given the spectre that is the GTX 460 still towers over it, and can be had for only £20 or so more, you're better offer forgoing a few pints and grabbing one of those instead.

3. AMD Radeon HD 6850 (£135)

best graphics cards

Launched at the same time as its slightly costlier sibling, the Radeon HD 6870, the Barts XT powered Radeon HD 6850 graphics processor failed to impress at launch due almost entirely to its misguided pricing. For reference, the card originally shipped at £160, at a time when Nvidia was cutting the price of comparably-powerful GTX 460.

The Barts XT GPU was essentially a stop gap while AMD put the finishing touches to the Cayman GPU that can be found powering the incredible Radeon HD 6950 GPU. Beyond a more power-efficient core, and a slightly reworked tessellation engine, this cards only real claim to fame is that it was the first of the second-generation of DX11 graphics cards.

The fact that it failed to comprehensively better the Radeon HD 5850 its name would suggest it was meant to replace also grated, and even though it's officially supposed to be heading for end of life status, you'd still rather pick up a 5850 to one of these.

Time has started to treat the Radeon HD 6850 a little fairer though, and a good £20-30 has been shaved off the launch price to make for a slightly more appealing pixel-pusher.

Better value cards can still be had for less, while those looking for real power should set their sights on the Radeon HD 6950. Having said that, if you can pick up the 6850 at closer to £120, then it'll give the budget-licious GTX 460 a run for its money, and is worth grabbing.

2. Nvidia GeForce GTX 560 (£200)

best graphics card

Given how the GTX 460 has come to define the budget end of the graphics card market, it was only a matter of time before Nvidia released its successor, the GTX 560 Ti. And while it would have been nice to see this card roll out £50 cheaper than this, given the technology throbbing away inside its black exterior, that would be a lot to ask.

In actual fact this card is pitched more against the GTX 470, both in terms of pricing and performance. The re-engineered Fermi core has been refined and tweaked to produce an impressive graphics processor, packing 384 CUDA cores and 64 texture units into its monolithic design.

The GTX 560 Ti may lack the vapour chamber cooling of the top-end cores, but that doesn't stop it being an incredible little overclocker. Anyone looking to get a bit more performance out of their quality graphics card has a decent amount to play with here too.

This is an impressive graphics card, and if you have a particularly unreasonable allegiance to Nvidia then you're not completely off the money. The problem is, the AMD Radeon HD 6950 has a serious trick up its sleeve, performs where it needs, and can be had for only £10 more. And when you're looking at this much cash, that's money you really should spend.

1. AMD Radeon HD 6950 (£210)

best graphics card

Every few years a graphics card is released that sums up that generation better than any other. We're talking about the likes of the 8800GT and the budget-focused Radeon X1950 Pro. Cards that transcend their immediate markets and time frames and stand up for years to come as being bang on the money.

The AMD Radeon HD 6950 defines the market. Cheaper cards look up to it for its raw power, while the top-end cards are mindful of the sheer value it offers and are rightly fearful of what can be achieved when two are cajoled together in CrossFire.

The Radeon HD 6950 isn't a subtle reworking of the first generation of DX11 graphics in the same way that Barts is, but rather a complete reworking of the inner logic of AMDs graphics chips. And its an incredible card for it.

The performance is incredible at console-breaking 1080p resolutions, and in DX11 games it punches well above its weight. If you're looking for a no-nonsense card that will last you until DX12 rolls out, and don't plan on running insanely high resolutions, this is the card for you.

Those with the stomach for it will discover that they can turn their £200 Radeon HD 6950 into a fully fledged 6970 with a BIOS flash as well. Here is a card that both AMD and Nvidia are going to be hard pushed to beat any time soon. Simply incredible.

The following five cards represent the pinnacle of modern graphics performance. These are cards that are beyond the sweet spot of what's needed in order to enjoy the latest games at reasonable resolutions.

The following cards are essentially here to fill the niches in gamers requirements that the likes of the Radeon HD 5960 cannot satisfy. Here we're talking about outputting to 27-inch and 30-inch panels that have a native resolution of 2560 x 1600. Or multiple screen displays made up of three or more 22-inch or 24-inch panels.


This end of the market is complicated somewhat by the advances made in SLI and CrossFire. These twin-graphics card pairing technologies now genuinely provide the performance improvements over single cards that you would hope for – 90-95% is often the norm.

A pair of cheaper cards in SLI can outperform the following cards too, which means the requirement of having a supporting motherboard is generally the only thing that is holding you back.

5. AMD Radeon HD 6970 (£260)

best graphics cards

Given that the AMD Radeon HD 6970 is simply a faster spin of the Radeon HD 6950 with more of everything that makes that card so great, surely this then is a fine card worthy of the money? Not quite.

The problem is, while Radeon HD 6950 is slower than this, it's only just slower. At the higher resolutions, which is all that really matters for these high-end cards, we're talking a few frames per second different at most.

In real terms you'd be hard pushed to spot such differences, which means that the extra £50 you pay for this over the cheaper card doesn't really pay off. That and the fact that the first slew of Radeon HD 6950s can be flashed to essentially turn them into 6970s conspire to make this a card that doesn't quite add up.

The fact of the matter is: if you want the kind of performance that will drive a bigger display, you're going to need to spend more than this.

4. Nvidia GeForce GTX 590 (£584)

best graphics cards

The Nvidia GeForce GTX 590 is a dual-GPU graphics card, similar in performance and guise to the Radeon HD 6990 that proceeded it into the market by roughly a month.

This means that inside that huge cooler you'll find a pair of GTX 580 cores humming away at not-quite GTX 580 speeds. In real terms that equates to a whopping 1024 CUDA cores, 96 ROPS and access to a healthy 3GB of GDDR5.

In order to fit a pair of GPUs inside a single card though, speed sacrifices have had to be made.

In the case of the GeForce GTX 590, that means dropping the core clock from the GTX 580's 772MHz down to a 607MHz. The memory speed too has been slashed, from 1.02GHz down to 853MHz.

As with the Radeon HD 6990, anyone looking for the ultimate in performance should really look at pairing up two GTX 580s, although that will cost you considerably more.

We've given the Radeon HD 6990 the slight nod over the GTX 590 simply because it does have the lead in the titles that matter, however slight that actually is.

3. AMD Radeon HD 6990 (£550)

best graphics cards

The Radeon HD 6990 is the second of two cards that utilise a pair of graphics processors to produce framerates that are out of this world. Although as you can see, this does come at a obvious downside – the pricing.

The Radeon HD 6990 utilises a new graphics processor, named Antilles, which is a slightly tweaked take on the Cayman core that can be found in the Radeon HD 6870, albeit not at the full speed of that GPU. This means you get the full 4GB of GDDR5 memory, strong tessellation performance and a stunning 3,072 streaming processors for handling your games.

Unfortunately, in order to cram two GPUs into the power footprint of a single graphics card, the core clock speed has had to be reduced from 880MHz to 830MHz. Similarly, the memory is running at 1.25GHz as opposed to the 1.375GHz of the 6970.

In truth there really isn't a lot between this and the previous card, the GTX 590 – they offer roughly the same performance and cost about the same.

If you're in the market for a dual-GPU graphics card, then your preference essentially comes down to whether you prefer AMD's drivers and support, or Nvidia's.

2. Nvidia GeForce GTX 570 (£280)

best graphics card

Value for money may seem like a strange metric to pull out of the hat at this end of the graphics market, but the GTX 570 does a decent turn at making your investment feel prudent rather than simply excessive.

Essentially a replacement for the soon to be retired GTX 480, here is a card that essentially does everything that Nvidia's last-generation top dog did, but without the problems that card suffered from when it shipped.

The cooler is quiet and more efficient, and the raw power on offer from this sub-£300 card is stunning. This is a slightly cut down version of the GTX 580, losing one Streaming Multiprocessor (or 32 CUDA cores to put it another way) and 8 ROPs.

The GTX 570's core operates at 732MHz as opposed to the GTX 580's 772MHz, while the 1,280MB of GGDR5 memory speeds along at 950MHz, as opposed to the GTX 580's 1,002MHz.

For the money, there isn't a lot out there that can touch the GTX 570 in terms of pure performance, apart from possible a pair of GTX 460s in SLI – but such a configuration does require an SLI motherboard.

1. Nvidia GeForce GTX 580 (£395)

best graphics cards

The GeForce GTX 580 is the fastest single-GPU graphics card currently available, and probably will be the only option for some time to come yet.

Created as the spiritual successor to the much-maligned GTX 480, Nvidia took the problems it had with its first DX11 graphics card and corrected them.

This means you get a full-fat core boasting 512 CUDA cores and 48 ROPS, not one that has been cut down to achieve better yields. And all running at a healthy 772MHz with a 1,002MHz memory bus for the 1,384MB of GDDR5 memory.

Not everyone needs the power of a GTX 580 – only those with serious screens to power. This is a market targeted by the twin-GPU Goliaths that are the AMD Radeon HD 6990 and Nvidia' own GeForce GTX 590.

The GTX 580 still has the nod though, because those cards have had to be throttled back to fit on a single card, while here you know nothing is being constrained. This is still the most sensible option for anyone looking for unfettered speed from a single GPU.



Updated: 15 best graphics cards in the world today

Posted: 07 Apr 2011 08:39 AM PDT

The PC is lining up for a brilliant year. It's already been highlighted as the platform of choice for for the likes of Bulletstorm, Crysis 2 and Dragon Age 2 to name but a few. And as the consoles stagnate due to their ageing technology, it's something that's only set to continue.

In order to experience such games at their best though, you're going to need to ensure you have a machine that's up to the task. And by machine we're primarily focusing on your graphics card.

It's the graphics card that does the serious work when it comes to rendering your games, and the more effects and higher resolutions you throw at it, the more is asked of that graphics card.

It's important to pick your graphics card so that it works well with your display, or displays. There's no point for instance, trying to power a 30-inch screen with the likes of a GeForce GTS 450. By the same notion, running a standard 20-inch screen with the likes of Radeon HD 6990 won't begin to tap into the cards power.

As a quick rule of thumb, whatever you spent on your screen, you're going to want to spend a similar amount to power it. Roughly.

The question is, which one of the many graphics cards out there should you actually spend your hard earned cash on? Here TechRadar highlights the top fifteen cards worth considering. We cover the notable cards from the last generation, the best all-rounders for most PC gamers, and the £550 monsters that can handle multi-screen outputs.

In this guide though we'll let you know what's hot, what's cool and what the fastest GPUs available right now and worthy of your time are.

Best of all, because we're now enjoying the second generation of DirectX 11 hardware, every card we look at here is capable of rendering the latest, funkiest DirectX 11 games.

So how does your graphics card stand in our countdown, and is it time for an upgrade? Well, there's only one way to find out…

ATI radeon hd 5970

There are a lot of terms and acronyms that get bandied around when talking about graphics cards, and not a lot of explanation to go along with them.

Before we delve into the meat of the feature let's take a minute to clear things up a little.

GPU - This is the graphics processing unit, the chip at the heart of the graphics card. Many cards use the same GPU but partner it with different components and at different clockspeeds to produce slower or faster graphics cards.

GDDR - Graphics Double Data Rate memory is the specific kind of memory that is used on graphics cards.

ROPs - The Render Output unit comes into play during the final stages in the rendering process, bringing together the data from each of the memory buffers in the graphics card's local memory. The more of them you have, the better off you are.

CUDA - The Compute Unified Device Architecture is a coding language Nvidia invented to allow parallel computing on its range of GPUs. From its 8 series upwards all its cards can use CUDA to speed up parallel processing applications, such as video encoding, in a faster way than your computer's CPU.

PhysX - Originally an accelerator chip and software layer from the small company Ageia, Nvidia bought up PhysX and has now applied it to its GPUs, again from the 8 series forward. It allows for more advanced physics simulations, such as liquid or cloth, in games that have been coded with the PhysX software included.

Crossfire and SLI - These are the relevant multi-GPU configurations from both AMD and Nvidia. Both allow multiple graphics cards to be connected together to increase the rendering performance. Historically this has been fraught with driver issues and diminishing returns for the extra cards, but as the latest cards have been released we are getting closer to doubling the performance by adding in a second card.

PCB - The Printed Circuit Board is the physical board that graphics cards (and all other micro-electronics) have their components attached to. The boards are printed with conductive pathways between the relevant components instead of using physical wires.

DirectX - Microsoft's DirectX is a collection of its own proprietary APIs (application programming interfaces) for dealing with multimedia tasks on its own operating systems. The Direct3D part is specifically to do with 3D graphics and utilises hardware acceleration if there is a GPU in place to take advantage of it.

Tesselation - This is one of the key buzzwords to come from Microsoft's latest graphical API, DirectX 11. Essentially it is designed to add extra geometry to a simple polygon using displacement maps to tell the GPU where to raise and lower parts of the polygon as the graphics card computes the data. The idea being to add geometry to objects in a game world without significantly impairing performance and it is set to become a key battleground in the graphics war in the coming years.

The first generation of DirectX 11 graphics cards boasted some notable GPUs. Here's are low-down of the cards that still manage to be relevant even after the second slew of cards settles in:

5. Nvidia GeForce GTS 450 (£85)

Best graphics cards

If 1680 x 1050 is the mass-market gaming resolution of choice, then the GTS 450 is opium for the masses.

This tiny powerhouse (well, it's still dual-width, but pleasingly short) is capable of feats beyond its £80-£90 price tag. What's more, in SLI, you'll see massive performance gains, making the dual-card upgrade path a realistic and impressive option for budget systems.

The basic GeForce GTS 450 is, architecturally, about half of a GeForce 460 with a higher clockspeed and a narrower memory bus.

However, the GTS 450 has the advantage over the GTX 460 of being smaller and requiring less power, which makes it a strong candidate for that SLI set-up

It is, however, now pitched directly up against the HD 5750 in pricing terms thanks to the on-going Nvidia/AMD graphics card price wars. And that is a card the GTS 450 happily beats into submission in any benchmark you throw at it.

4. AMD Radeon HD 5770 (£100)

best graphics cards

For budget-conscious gamers, the HD 5770 should be a serious consideration. Have a scout around the online retailers, and you'll see that examples can be had for less than £100 now.

Offering competent performance at the mainstream 22-inch resolution of 1680 x 1050, it also comes with the promise of cool-running, quiet operation – a trademark of AMD's last-gen design philosophy.

However, try to crank the shinier graphical elements – such as Anti-Aliasing and Anisotropic Filtering – too high, and the card starts to run out of grunt.

AMD's EyeFinity technology, which enables multi-screen scaling, is a very real option with the 5770, though we wouldn't recommend the 5770 for multi-screen gaming; it just doesn't have the throughput for gaming at huge resolutions.

But the really interesting thing about the HD 5770 is what its price represents. At these low prices, our thoughts turn to CrossFire setups. For under £200, you can net yourself a twin-card setup that offers kick-ass performance at mid-range resolutions.

If you're content with that 22-inch monitor and want zingy performance on a budget, this CF setup is probably the cheapest way to achieve it... Oh, and did we mention the 5770 is DX11 capable? Yum.

3. Nvidia GeForce GTX 470 (£160)

best graphics card

Not so hot on the heels of Nvidia's first DX11 graphics cards came the GeForce GTX 470, a cut-down version of the GF100 GPU the green company is rightfully proud of.

Given the larger pricetag of its big brother, the GTX 480, this represents the most affordable high-end Fermi card of the first generation.

Like the rest of the Fermi range, the 470 has seen some nifty price-cuts, which means it can now be had for £160. This makes the cheapest 470s at just £30 more expensive than the GTX 460 1GB, the new midrange king. That makes it a pretty compelling prospect right now.

In addition, at the native 22-inch resolution of 1680 x 1050, this card is a fair way ahead of the HD 5870. When things get cranked up though, it starts to lose its competitive edge against AMD's upper-midrange peer.

Indeed, in our World in Conflict benchmark it actually dropped behind. Still, thanks to its Fermi roots, the GTX 470 has still got the tessellation goods and this promises some future-proofing.

This card has been superseded by the likes of the GTX 560 Ti though, which means that it's not going to get replaced once stock levels do become exhausted. Worth considering while you can find it, though.

2. AMD Radeon HD 5850 (£140)

best graphics cards

The Radeon HD 5850 came out shortly after AMD's flagship DirectX 11 graphics card, the Radeon HD 5870.

As with many graphics families, this second-tier offering represented – and still represents – incredible value for money thanks to offering up the same feature set and only a slightly reduced specification from the top-of-the-range card, albeit at a much more attractive price point.

When this card cost £225, it offered great value for money. These days it's considerably cheaper than that, and has had to weather competition from both AMD and Nvidia, but it still puts it a good show in the latest games.

There are also rumours that more affordable versions of the Radeon HD 5850 are in the works, so be prepare to shop around to bag a bargain.

1. Nvidia GeForce GTX 460 1GB (£130)

best graphics cards

The 1GB version of the GTX 460 (there's also a noticeably less powerful 768MB iteration) started at a price-point that undercut its immediate Radeon-shaped competition by a fair margin, and that's only got better as the months have gone by.

The GTX 460's rejigged GF100 GPU though may sound like Nvidia has just chopped the GTX 480's chip in half, with only seven streaming multiprocessors (SMs) against the older card's fourteen, but inside, things have most definitely changed.

These SMs are the units that hold the myriad CUDA cores (previously known as shader processors), special function units (SFUs), texture mapping units (TMUs) and the polymorph engines that contain the all-important tessellation grunt.

The SMs of the GF100 chips contain a maximum of 32 shader cores, four SFUs and four TMUs. In the GTX 460 chip though Nvidia has squeezed another 16 CUDA cores into each SM and upped the SFU and TMU counts to eight per SM.

Each of these SMs has also had some CPU-like extra multi-threading goodness injected into them in the shape of an extra couple of dispatch units in each of them.

What this means is awesome midrange performance, and respectable performance at resolutions higher than 1680 x 1050. Pair a couple up for SLI kicks though, and you get a punchy setup that can rival Nvidia's own GTX 580.

These mid-range graphics card represent the sensible money for most PC gamers; combining great raw performance with a price tag that won't make you pass out.

If you're looking to power a screen with a native resolution of 1,680 x 1,050 or 1,920 x 1,080, then you really don't need to get anything more powerful than this. At least given the current slew of games.

These cards also hold an ace up their sleeve if you have an SLI or CrossFire motherboard in your rig, because they enable you to boost the performance of your machine by adding in a second card as your needs progress.

The performance is incredible at console-breaking 1080p resolutions, and in DX11 games it punches well above its weight. If you're looking for a no-nonsense card that will last you until DX12 rolls out, and don't plan on running insanely high resolutions, this is the card for you.

Those with the stomach for it will discover that they can turn their £200 Radeon HD 6950 into a fully fledged 6970 with a BIOS flash as well. Here is a card that both AMD and Nvidia are going to be hard pushed to beat any time soon. Simply incredible.

The following five cards represent the pinnacle of modern graphics performance. These are cards that are beyond the sweet spot of what's needed in order to enjoy the latest games at reasonable resolutions.

The following cards are essentially here to fill the niches in gamers requirements that the likes of the Radeon HD 5960 cannot satisfy. Here we're talking about outputting to 27-inch and 30-inch panels that have a native resolution of 2560 x 1600. Or multiple screen displays made up of three or more 22-inch or 24-inch panels.


This end of the market is complicated somewhat by the advances made in SLI and CrossFire. These twin-graphics card pairing technologies now genuinely provide the performance improvements over single cards that you would hope for – 90-95% is often the norm.

A pair of cheaper cards in SLI can outperform the following cards too, which means the requirement of having a supporting motherboard is generally the only thing that is holding you back.

5. AMD Radeon HD 6970 (£260)

best graphics cards

Given that the AMD Radeon HD 6970 is simply a faster spin of the Radeon HD 6950 with more of everything that makes that card so great, surely this then is a fine card worthy of the money? Not quite.

The problem is, while Radeon HD 6950 is slower than this, it's only just slower. At the higher resolutions, which is all that really matters for these high-end cards, we're talking a few frames per second different at most.

In real terms you'd be hard pushed to spot such differences, which means that the extra £50 you pay for this over the cheaper card doesn't really pay off. That and the fact that the first slew of Radeon HD 6950s can be flashed to essentially turn them into 6970s conspire to make this a card that doesn't quite add up.

The fact of the matter is: if you want the kind of performance that will drive a bigger display, you're going to need to spend more than this.

4. Nvidia GeForce GTX 590 (£584)

best graphics cards

The Nvidia GeForce GTX 590 is a dual-GPU graphics card, similar in performance and guise to the Radeon HD 6990 that proceeded it into the market by roughly a month.

This means that inside that huge cooler you'll find a pair of GTX 580 cores humming away at not-quite GTX 580 speeds. In real terms that equates to a whopping 1024 CUDA cores, 96 ROPS and access to a healthy 3GB of GDDR5.

In order to fit a pair of GPUs inside a single card though, speed sacrifices have had to be made.

In the case of the GeForce GTX 590, that means dropping the core clock from the GTX 580's 772MHz down to a 607MHz. The memory speed too has been slashed, from 1.02GHz down to 853MHz.

As with the Radeon HD 6990, anyone looking for the ultimate in performance should really look at pairing up two GTX 580s, although that will cost you considerably more.

We've given the Radeon HD 6990 the slight nod over the GTX 590 simply because it does have the lead in the titles that matter, however slight that actually is.

3. AMD Radeon HD 6990 (£550)

best graphics cards

The Radeon HD 6990 is the second of two cards that utilise a pair of graphics processors to produce framerates that are out of this world. Although as you can see, this does come at a obvious downside – the pricing.

The Radeon HD 6990 utilises a new graphics processor, named Antilles, which is a slightly tweaked take on the Cayman core that can be found in the Radeon HD 6870, albeit not at the full speed of that GPU. This means you get the full 4GB of GDDR5 memory, strong tessellation performance and a stunning 3,072 streaming processors for handling your games.

Unfortunately, in order to cram two GPUs into the power footprint of a single graphics card, the core clock speed has had to be reduced from 880MHz to 830MHz. Similarly, the memory is running at 1.25GHz as opposed to the 1.375GHz of the 6970.

In truth there really isn't a lot between this and the previous card, the GTX 590 – they offer roughly the same performance and cost about the same.

If you're in the market for a dual-GPU graphics card, then your preference essentially comes down to whether you prefer AMD's drivers and support, or Nvidia's.

2. Nvidia GeForce GTX 570 (£280)

best graphics card

Value for money may seem like a strange metric to pull out of the hat at this end of the graphics market, but the GTX 570 does a decent turn at making your investment feel prudent rather than simply excessive.

Essentially a replacement for the soon to be retired GTX 480, here is a card that essentially does everything that Nvidia's last-generation top dog did, but without the problems that card suffered from when it shipped.

The cooler is quiet and more efficient, and the raw power on offer from this sub-£300 card is stunning. This is a slightly cut down version of the GTX 580, losing one Streaming Multiprocessor (or 32 CUDA cores to put it another way) and 8 ROPs.

The GTX 570's core operates at 732MHz as opposed to the GTX 580's 772MHz, while the 1,280MB of GGDR5 memory speeds along at 950MHz, as opposed to the GTX 580's 1,002MHz.

For the money, there isn't a lot out there that can touch the GTX 570 in terms of pure performance, apart from possible a pair of GTX 460s in SLI – but such a configuration does require an SLI motherboard.

1. Nvidia GeForce GTX 580 (£395)

best graphics cards

The GeForce GTX 580 is the fastest single-GPU graphics card currently available, and probably will be the only option for some time to come yet.

Created as the spiritual successor to the much-maligned GTX 480, Nvidia took the problems it had with its first DX11 graphics card and corrected them.

This means you get a full-fat core boasting 512 CUDA cores and 48 ROPS, not one that has been cut down to achieve better yields. And all running at a healthy 772MHz with a 1,002MHz memory bus for the 1,384MB of GDDR5 memory.

Not everyone needs the power of a GTX 580 – only those with serious screens to power. This is a market targeted by the twin-GPU Goliaths that are the AMD Radeon HD 6990 and Nvidia' own GeForce GTX 590.

The GTX 580 still has the nod though, because those cards have had to be throttled back to fit on a single card, while here you know nothing is being constrained. This is still the most sensible option for anyone looking for unfettered speed from a single GPU.



Panasonic adds iPlayer to 2011 Viera TVs

Posted: 07 Apr 2011 08:29 AM PDT

Panasonic has announced that iPlayer will be making its way to the web-connected 2011 Viera TV line up.

Unfortunately, even internet-ready older Viera models won't be getting the BBC's much-loved catch up service.

Only the 24 new flat-panel Vieras launching this year will be compatible, both LCD and Plasma models, in screen sizes ranging from 32 to 65-inches.

To the cloud!

iPlayer will be part of Panasonic's cloud-based connected TV service, imaginatively named Viera Connect.

As well as iPlayer, it offers interactive games, access to YouTube and Picasa, Skype and Twitter apps.

If you have an older Panny TV and are desparate for iPlayer, fear not! You can access the service using a number of set top boxes and some games consoles, including the Nintendo Wii and PlayStation 3.

Facebook to become major force in Hollywood?

Posted: 07 Apr 2011 08:27 AM PDT

Facebook could well become a major force in Hollywood movie distribution, according to one of the social network's primary investors.

Venture capital firm Accel Investing is Facebook's second-largest shareholder after founder Mark Zuckerberg - and is currently directing a significant amount of capital into certain Hollywood studios, hoping that Facebook will become an increasingly important movie distribution force in the near future.

Facebook goes to the movies

Accel recently dropped a cool $40 million investment in Legendary Pictures, the producer behind recent box-office favourites such as The Dark Knight.

Meanwhile, Warner Bros is already trialling movie rentals using Facebook, with The Dark Knight already available for US viewers to watch via Zuckerberg's website - for a fee.

Accel exec Jim Breyer clearly thinks (and hopes) that Facebook will become an increasingly valuable distribution system for content producers in the near future, recently explaining to All Things Digital:

"We believe there are a number of extraordinary opportunities that sit at the intersection of content and social networking platforms like Facebook," hoping that Facebook will be able to provide Tinseltown with "multichannel distribution capabilities for video content beyond classic theatrical and television release."

"At the heart of what Facebook is trying to do is enable outstanding content and application developers to develop breakthrough video and media applications," the Facebook investor added.
