nVidia GeForce GTX 200 Series review

GeForce GTX 260 - £299 inc VAT

Manufacturer: Nvidia

More than just a graphics card, the nVidia GeForce GTX 200 Series is no less than a secondary processor.

More than just a graphics card, the nVidia GeForce GTX 200 Series is no less than a secondary processor.

nVidia yesterday introduced the GeForce GTX 200 series of graphics processors. And this is no ordinary launch: with the nVidia GeForce GTX 200 Series, nVidia is giving a graphics processor a whole new role.

Every new graphics processing unit (GPU) ushers in new levels of realism and computational power, but don't call the GeForce GTX 200 Series simply "graphics cards". A little over 10 years after games such as Tomb Raider and GLQuake hit the scene, a new kind of GPU is being born. nVidia has designed more than just a DirectX10 board that makes games scream and Vista's Aero interface hum. The nVidia GeForce GTX 200 series is a secondary processor. It's a physics calculator. And it's about time.

The nVidia GeForce GTX 200 Series cards will sell in two flavours. The first, a high-end GeForce GTX 280 with 240 processors and 1GB of frame buffer memory, sells at around £450. (As expensive as that may sound - and it is - this is the consistent ceiling price for high-end consumer cards these days). The more "mainstream" model, the £299 GeForce GTX 260, ships in late June 2008 with 192 processors and a 896MB frame buffer.

What does that mean for these PCI Express 2.0 cards that pack 1.4 billion transistors? nVidia promises that the GTX 280 is 1.5 times faster than a high-end 8800 / 9800-series GPU. While our testing continues, we can tell you that EA's Crysis (review here) ran twice as fast at 1920 by 1200-pixel resolution with 4x Anti-Aliasing compared to Asus' EN8800GT Top (on average, 8800GT cards cost about £125. For those doing the maths at home: you're getting 2x the performance for roughly 3x the price).

GPU vs CPU

The new nVidia GeForce GTX 200 GPU is the result of smart collaborations. nVidia's engineering pool, now loaded with the newly acquired AEGIA team, has created a plug-in card designed to amplify system performance in many ways.

The Compute Unified Device Architecture (CUDA) shows that nVidia's GPU is capable of a much more than rendering death-dealing aliens. In February 2007, nVidia released the software developers' kit (SDK) that allowed 8800-series owners to develop programs that push the GPU. A quick visit to nVidia Cuda Zone reveals applications that do everything from complex financial calculations to mapping the human genome.

Thanks to the SDK's release, others are creating applications that are a little less academic. A great example is Elemental Technologies' upcoming BadaBOOM Media Converter, a video encoder that runs entirely off an nVidia GPU - as opposed to just about every other encoder around that's central processing unit (CPU) bound.

nVidia promises video encoding speeds at least twice as fast as a CPU-bound one. Initial tests in our labs could verify the claim: a two-minute clip optimised for the iPod touch (480 by 320-pixel resolution, AAC audio) took about 24 seconds. That same video, compressed using AVS Video converter 5.5, took 56 seconds. That's impressive, no doubt, but it really is an apples-to-oranges comparison. You see, for the fairest test, we'd need to have the provided BadaBOOM software (which, by the way, works amazingly well) have a toggle to switch between GPU encoding and CPU encoding.

We are, however, currently running other lab tests for a better read on the difference between GPU and CPU computing and will update you as soon as we have the final results.

nVidia GeForce GTX 200 Series Expert Verdict »

There are currently no technical specifications recorded for this product.

Gaming remains the most obvious reason to buy these boards. But here are a few caveats before you run to a store (physical or virtual) for the best deals. Both cards are dual slot design (roughly the same size and girth as the 9800 GX2 cards) so make certain that you have a wide enough case (or don't mind cutting through the hard drive cage just to accommodate a graphics card. Even though the new card promises energy efficiency for the tasks at hand (according to nVidia, 25 Watts when idling in 2D mode and maxing out at 236 Watts), you still need to make certain that your power supply is rigged to juice these boards. The GTX 260 requires two six-pin power connectors and the GTX 280 needs a six-pin and eight-pin connector. Crack your case before buying.
