Buying Guide: Best graphics card under £150: 8 reviewed

By TechRadar, published 27-10-2011

Best graphics card under £150: 8 reviewedGraphics cards are so important - theyproducing the biggest performance variable in a desktop PC.We've capped the pricing at £150.If you only upgrade one component in your PC, make it your graphics card. It's going to have the most dramatic effect to your video playback, gaming frame rates and graphical quality.Before we delve into the group test, there are a few things to mention. If you're sitting on a powerful last-gen GPU, you're faced with quandary: buy another of my existing card for a cheap SLI/CrossFire setup, or start again with a new single GPU.In general, we'd recommend the newer single card, but it does depend on what you've got to work with in your existing rig. Nvidia's GTX 280s have retained their value sickeningly well, yet can't h...

Review: XFX HD 6850

By TechRadar, published 31-08-2011

To be honest we were rather unforgiving of the HD 6850, at launch it was pricing itself almost out of the market. It was going toe-to-toe with Nvidia's 1GB GTX 460 which, at the time, just about had it pipped in performance terms. It was also a little pricier than the GTX 460, coming in around the £160 mark. Again though time has been kind to the HD 6850. The price has dropped a huge amount, indeed AMD recently announced a further price-drop bringing the card down to less than £120, which for a spec like this is a serious bargain. AMD's constant driver updates too have meant that performance has increased over time as well. The Barts Pro GPU core at the heart of the HD 6850 is a reworking of the Cypress Pro that made the HD 5850 such an impressive card back in the day. It doesn't have th...

Buying Guide: 10 top gaming graphics cards compared

By TechRadar, published 18-06-2011

There's one component in your machine that will be superseded by faster and more powerful versions quicker than any other, and that's the graphics processor. The graphics card is the supermodel part of any modern gaming PC. It, more than anything else, makes your games look beautiful and run as smoothly as a baby's velvet smoking jacket. So, if you're a gamer and you've got a bit of cash to spend, forking out the lot on a new graphics card is the best way to up the frame rate of your favourite games and make the girls think you're attractive, right? Unfortunately, that's not necessarily the way the graphics game works. The top-performing rigs are always the most well balanced. Put a Ferrari engine into a Mk1 Golf GTi and it will go fast, sure, but you'll fly off the first corner you come t...

Arma 3 Announced For Summer 2012, First Screenshots

By MaximumPC, published 19-05-2011

After weeks of puzzles and hinting, Czech developer Bohemia Interactive has confirmed that a follow-up to its landmark military simulation game, Arma 3, is in development. It’s still a PC exclusive, it’s set somewhere in the Mediterranean, and it’ll retain the fine, sandboxy, multiplayer-friendly, emergent warplay that we expect from the franchise with some key improvements. Within: I dissect every detail of the announcement, play Where In The World Is Arma Sandiego?, and change my pants. Arma 3?s story, as described by the press release: “After years of intense warfare against Eastern armies, Europe has become the last stand for the battered NATO forces. On the verge of being driven into the sea, NATO command embarks upon a most desperate measure. In the hope of seizing what seems...

Review: Sapphire AMD Radeon HD 6570

By TechRadar, published 05-04-2011

With its latest two releases, the AMD Radeon HD 6670 and this AMD Radeon HD 6570, AMD is ducking below the £100 mark.AMD has long been the value proposition when it comes to gaming. Whether it's processors or graphics cards, you can always rely on it to give you options no matter what your cashflow looks like. Indeed, with this little card at around £50, it's seriously limboing that £100 price point.So we've seen the HD 6570's big brother in action and, ignoring the more tantalising prospect of the XFX Radeon HD 5770, it's not a bad little budget gamer's card. Based on the same essential architecture, this slightly slower £50 version ought to be pretty good value too.They're both running the same new AMD GPU and, in Sapphire clothing, they're both set on a full-size slab of PCB with an...

Review: Sapphire AMD Radeon HD 6670

By TechRadar, published 05-04-2011

We've been getting hot under the GPU-collar for the top end of the graphics market in the last few months, with the release of both AMD's Radeon HD 6990 and Nvidia's GeForce GTX 590 dual-GPU monoliths. But we still love a cheeky, cheap GPU like the AMD Radeon HD 6670.It's all very well talking about £600 graphics cards that need PC cases the size of Andre the Giant to house them, and a mini Arc reactor to keep them powered, but how many of us are actually going to drop a month's wages on such a pixel-pushing behemoth?More likely you're going to be looking at a maximum outlay of around £150-£200. And currently there's a lot of graphics processing power available all the way down the price spectrum too.AMD though has come in, GPUs-blazing, at a sub-£100 price point with its latest Direct...

AMD Reportedly Prepping Mid-Range Radeon HD 6790

By MaximumPC, published 29-03-2011

Go ahead and pat yourself on the back if you waited this long to upgrade your graphics card, you now have a bunch of next generation parts to choose from, including dual-GPU cards from both AMD and Nvidia. These two heavyweights aren't finished, either. According to reports, AMD is working on a mid-range Radeon HD 6790 videocard built around the 40nm Barts GPU. It should end up faster than the Juniper-based HD 5700, and perhaps nearly as fast as the 6800 series. According to news and rumor site Fudzilla, the HD 6790 will sport 800 stream processors organized in 10 streaming multiprocessor units. That means there will be two blocks of 400 stream processors with a dispatch processor for each block. That's the same number as found in the HD 5770 (800 SPs), but with a different arrangement. Ot...

iPad 2 Benchmarks Blast Competition, Show Less-than-1GHz Processor Speed

By SlashGear, published 13-03-2011

A couple of things have come to light over the past few days, most of these lovely little tidbits coming out over the past 24 hours where the iPad 2 has been release out into the wild. The first of which we didn’t touch on for more than a few moments in our [early iPad 2 review a few days ago] – as you’ll see in our Geekbench result below, one point stands out pretty hard: the Processor. Instead of the 1GHz CPU in its head that it’s supposed to be, the iPad 2 is running at 894 MHz. In another couple tests by IOSnoops and AnandTech, as reported by Engadget, clocked the ARM Cortex a( in at right around 900HMz as well. Apple you scoundrels! We’re not too worried about it though, as this beast has continued to be put through the tricks and traps of benchmarking...

AMD vs Nvidia: 10 Videocards Go Head-to-Head

By MaximumPC, published 02-11-2011

A new generation of GPUs from Nvidia and AMD has hit the streets. Both camps are offering incredible performance and the widest array of features ever before seen in graphics cards. But, inevitably, each side brings its own unique strengths and weaknesses. What better way to determine the performance champ than by letting this season’s new crop of cards duke it out in the various price categories? On one side is AMD, the self-proclaimed master of efficiency, looking to hold onto the glory it grabbed when it shipped the original Radeon HD 5870—a surprise contender that knocked former champ Nvidia to the canvas at the time by offering DirectX 11 feature sets at impressive performance levels without requiring a nuclear reactor to power it. On the other side is Nvidia, looking to score a ...

Review: Palit GeForce GTX 560 Ti Sonic

By TechRadar, published 02-11-2011

Affordable and factory overclocked, Palit's GeForce GTX 560 Ti Sonic could be the ideal iteration of Nvidia's latest mid-range Fermi.The GeForce GTX 560 Ti caused a bit of a stir last month when it first hit our test benches. We were, and still are, fans of the GTX 460 and were hoping for more of the same graphical goodness in this next generation. Unfortunately though it doesn't hold as special a place in our heart as the GTX 460 though, but that's actually nothing to do with the card itself. It's still a speedy little daemon, and it's still coming in at the price/performance sweetspot of £200.The issue here is that the market has moved onwards since the inception of the GTX 460, or more specifically the competition has moved on.There was nothing to touch the original mid-range Fermi whe...

Review: Sapphire Radeon HD 5750

By TechRadar, published 02-11-2011

The HD 5750 is not a rampaging powerhouse. It can run games at 1,680 x1,050, but don't expect searing frame rates, especially when anti-aliasing and anisotropic filtering are on the cards.Moreover, DX11 effects, such as Tessellation and Multi-thread Rendering, require the kind of resource budgets the 5750 simply can't raise. With its narrow memory bus and a GPU that pales in comparison to AMD's other offerings, it struggles in these tests.Market changes mean that things have got a little better for the HD 5750, however. Just a month or so back, it was priced similarly to Nvidia's GTS 450, the raw grunt of which it simply can't match. It's come down a bit in price now though, and can be found for around £15 cheaper than the GTS 450, and its bigger brother, the HD 5770. But still that £15 ...

Review: PNY GeForce GTS 450 1GB

By TechRadar, published 02-11-2011

The GTS 450 offers mainstream gaming at an affordable price-point. This tiny powerhouse (well, it's still dual-width, but pleasingly short) is capable of feats beyond its £100 price tag. What's more, in SLI, you'll see massive performance gains of 80 to 90 per cent, making the dual-card upgrade path a realistic and rewarding option for budget systems. It bears architectural similarities to its bigger brother, the GTS 460, but with half the memory bandwidth and half the CUDA cores. What's impressive is that it doesn't offer half the performance in DX10 games, which it's perfectly happy with. Start throwing DX11 at it though, and it begins to run out of puff in fairly short order. The market has moved around the GTS 450. Initially priced against AMD's HD 5750 (which it beats into a cocked h...

Review: XFX Radeon HD 5770

By TechRadar, published 02-11-2011

AMD's pokey little mid ranger, the HD 5770, has been around for some time now. AMD is in the process of refreshing its range with the new 6-series cards, so we have to ask: is there still a place in the world for this little fellow? The answer is a resounding yes. At £100, the 5770 offers pretty decent value for money. And while this example from XFX trades HDMI for DisplayPort and a single DVI-D connection to keep the costs down, it's also a more elegant solution than most 5770s due to its single-slot nature and compact heatsink. The 5770 always did run cool and quiet – so who needs a chunky lump of copper on there taking up space and weight? When a card is this cheap, the upgrade path that Crossfire represents is an option too. Priced to compete with Nvidia's GTS 450, can it match it ...

Review: MSI GeForce GTX 470 Twin Frozr II

By TechRadar, published 02-11-2011

As with every generation of cards, the flagship sets sail before the hanky-waving crowds, and the slimmed down versions with slightly less capable GPUs follow in their wake. The GTX 470 came hot on the heels of the GTX 480, and with only marginally reduced architecture. It first launched at £290, in what seemed like a direct attack on AMD's excellent HD 5870. That's proper, high-end, enthusiast pricing, and you'd expect pretty hefty performance for that kind of outlay. But price cuts happen, and never more explosively than with the GTX 470. While you can plump for enhanced, 1.5GB versions with higher clockspeeds, this overclocked model from MSI offers sterling performance for just a shade over £200. Incredible! To put things into perspective, that's almost a ton cheaper than its May laun...

Review: HIS Radeon HD 6850

By TechRadar, published 02-11-2011

Take any card by either manufacturer and benchmark it next to its direct competitor from the other camp and there's at least one very clear conclusion to draw. Nvidia has the grunt, while AMD has the elegance. But another factor soon becomes apparent. When DX11 is added to the mix, AMD's performance doesn't tail off quite so quickly at the higher resolutions, and it's a point the HD 6850 makes very well indeed. This card represents a bit of an odd mixture. It seems to be built specifically to tackle DX11, and yet it still lacks the raw power to contend with its closest competitor in the price-range, the GTX 460 1GB, in DX10 applications. And of course, in DX11 games it outperforms the card it was designed to replace: AMD's own HD 5850. What's odd is that the HD 5850 hasn't dropped in price...

ATI Radeon HD 5770 1GB

By TheTechLounge, published 11-08-2010

The 5770 is a drop-in replacement for the 4870. It has the same basic amount of GPU processing power, albeit on a smaller process with much better power management. So the improvements are all elsewhere--DirectX 11 being the most prominent. It's also really, really cheap.
