F.E.A.R.

A shaders-saturated game, F.E.A.R. is sensitive to any increase in the pixel processors performance which directly depends on the GPU clock rate. This explains why the GeForce 7900 GTX is so much faster than the GeForce 7800 GTX 512 here. The new graphics card is as fast as two GeForce 7800 GTX working in SLI mode! The Radeon X1900 XTX is much lower than the GeForce 7900 GTX in low resolutions, but a little faster in high ones thanks to the more advanced memory controller. It should be noted that the performance of GeForce cards has grown considerably in F.E.A.R. with the driver suite released for the GeForce 7900.

We get a different picture when we compare the GeForce 7900 GTX SLI and the Radeon X1900 XT CrossFire: Nvidia’s solution does better in higher resolutions, at least in the 4x FSAA + 16x AF mode. The graphics memory performance has the biggest effect on the results at higher levels of antialiasing, and the GeForce 7900 GTX SLI is equal to the Radeon X1900 XT CrossFire in the 8x FSAA + 16x AF mode beginning from 1280x1024 resolution. Strangely enough, the SLI configuration with two GeForce 7900 GTX successfully contends with the Radeon X1900 XT CrossFire in two out of three resolutions in the 16x SLI AA mode, despite the use of super-sampling. Alas, neither of the multi-GPU configurations delivers a playable frame rate in this mode.
