The last test from 3DMark05 is traditionally the most difficult one, creating an enormous load on the pixel pipelines. The shaders employed here use almost every function from Shader Model 2.0. Despite its Shader Model 3.0 support, the GeForce 6800 Ultra is slower than the RADEON X850 XT Platinum Edition in all resolutions. The GeForce 6800 GT, however, is a good match for the RADEON X800 XL, being only 1fps behind in 1600x1200 resolution. The GeForce 6600 GT beats the RADEON X700 PRO across all resolutions. Of course, the GeForce 7800 GTX and the senior SLI configurations are beyond competition.
The GeForce 6 cards are faster than the RADEON X850/X800 cards of their class in all resolutions. The GeForce 7800 GTX ensures a playable frame rate in resolutions up to 1280x1024, while two such graphics cards would allow playing this scene comfortably in 1600x1200, if it were part of a real game. The overall performance scores seem to be correct: ATI RADEON X850/X800 cards look really better in 3DMark05, yet the 24 pipelines of the GeForce 7800 GTX just have no rivals at all.
