Showing a large scene, the Pier demo is dependent on the CPU speed. This can be observed with premium-class graphics cards even when full-screen antialiasing is in use. It’s only in the resolution of 1920x1200 pixels, which is still a luxury for many gamers, that the Radeon X1950 XTX offers a few extra frames per second relative to its GDDR3-equipped predecessor.
The Research demo doesn’t rely so heavily on the CPU, and the Radeon X1950 XTX delivers a nice performance boost in high resolutions that varies from 10% to 15%. This helps it keep close to the GeForce 7950 GX2, although having only one GPU with 16 texture-mapping units. On the other hand, this test doesn’t need a high fill rate since the action goes on in the closed and rather small environment of an underground base.
There is a performance boost in the HDR (FP16) modes, but it is now in the highest resolution of 1920x1200 that the speed gain is the smallest. As a result, the Radeon X1950 XTX is capable of delivering the same speed as the GeForce 7900 GTX, even though HDR support for ATI’s cards is not implemented optimally in Far Cry.
