Performance in First-Person 3D Shooters
Just as we had expected, the Radeon X1950 XTX has a 10% advantage over the Radeon X1900 XTX in 1600x1200 and none in 1280x1024. This advantage is not big enough to catch up with the GeForce 7950 GX2, but the gap is only 10% and the average speed of 113fps is more than enough for comfortable play in the highest resolution supported by this game with enabled 4x FSAA. If you want to have an even better-quality picture, switch into 6x FSAA mode. The Radeon X1950 XTX is strong enough to permit that.
Call of Duty 2
There is almost no gain from the use of GDDR4 in this game even in 1920x1200 resolution. The reason is that the game runs on a modified, yet still obsolete engine from Quake 3. The modification mostly comes down to hanging the engine over with numerous shader-based special effects. Those effects do not probably access the graphics memory too often, and the advantage of the new graphics card is just a few frames per second at best.
So, the new Radeon cannot challenge the GeForce 7950 GX2 in this test, but it keeps up with the GeForce 7900 GTX. Despite the old engine, the game is a heavy application and you can use FSAA on single-chip top-end graphics cards in resolutions not higher than 1280x1024.
