ATI seems to be definitively back in the high-end graphics cards arena. The R700 (2xRV770) is a very powerful GPU and with the latest Catalyst drivers that have brought OpenGL missing features, we have a nice graphics hardware!
Radeon HD 4870 X2 specifications:
– GPU: R700 / 55nm / 750MHz
– Shader processors: 1600 (2×800)
– Texture units: 80 (2×40)
– ROPs: 32 (2×16)
– Memory: 2Gb GDDR5 / 256-bit / 3600MHz effective
– Direct3D 10.1 and OpenGL 2.1

In most of benchmarks, the Radeon HD 4870 X2 dominates. But for that, the driver must provide adequate profiles to enable properly the use of both GPUs. And if an application is not in Catalyst’s profiles, the rendering is done with one GPU. Not really cool when you spent around 500 $US for a graphics card!
