F.E.A.R. Extraction Point

The new generation of CrossFire systems doesn't look brilliant here. The pair of Radeon HD 2900 XT 1GB cards (and of ordinary Radeon HD 2900 XT as well) is competitive against the GeForce 8800 Ultra in the resolutions of 16:10 format, but the minimum speed provided by such a pair is not high enough for comfortable play. Moreover, the CrossFire tandem acts up in 1600x1200, suffering a performance hit for some reason.

Tom Clancy's Ghost Recon Advanced Warfighter

Using the deferred rendering technique, this game is incompatible with full-screen antialiasing. That's why there are only anisotropic filtering results here.

Ghost Recon Advanced Warfighter proves to be fully compatible with the multi-GPU technology from AMD, and the new-generation CrossFire systems show their best here: the Radeon HD 2900 XT 1GB tandem surpasses the GeForce 8800 Ultra at every display resolution in terms of both average and minimum speed. And like in the previous tests, the same is going to be true for a pair of Radeon HD 2900 XT cards because the single Radeon HD 2900 cards deliver almost the same performance even at a resolution of 2560x1600 pixels. The game seems to have enough of graphics memory as well as of memory bandwidth ¨C the increased clock rate of GDDR4 memory installed on the Radeon HD 2900 XT 1GB is just not called for.
