Performance in Gaming Applications

Far Cry

NVIDIA’s GeForce 6800 GT lags behind the GeForce 6800 Ultra and ATI’s RADEON X800 XT in Far Cry, but surpasses the cheaper version of the X800, the RADEON X800 Pro. The overclocked GeForce 6800 GT is faster than the 6800 Ultra as well as the X800 XT and becomes the leader. The slowest version of the NV40, the GeForce 6800, cannot compete with the 6800 GT or the X800 Pro even when overclocked, but it easily leaves behind the top-end products of the last generation, the GeForce FX 5950 Ultra and the RADEON 9800 XT.

The GeForce 6800 GT remains ahead of the RADEON X800 Pro in the “eye candy” mode with enabled full-screen anti-aliasing and anisotropic filtering. At the overclocked frequencies, it is superior to the GeForce 6800 Ultra, too, but loses to the RADEON X800 XT, which is most efficient in this hard operational mode.

Having only 12 pixel pipelines, reduced frequencies and a smaller amount of the graphics memory, the GeForce 6800 falls behind the leaders more in higher resolutions – in 1600x1200 it even loses to the RADEON 9800 XT and the GeForce FX 5950 Ultra! Overclocking only helps it outperform the GeForce 5950 Ultra in the hardest mode, but the RADEON 9800 XT remains unreachable.

Probably, the 12-pipelined GeForce 6800 chip, like the RADEON X800 Pro, has a less efficient realization of the hidden surface removal technique compared to the chips with 16 pipelines, and it becomes another performance-reducing factor, especially in “hard” modes with full-screen anti-aliasing.
