Performance in Gaming Benchmarks: First-Person 3D Shooters

The Chronicles of Riddick

The CrossFire Xpress 3200 doesn’t boast any advantage over the earlier chipset despite the improved architecture and doubled number of PCI Express lanes. This is not a wonder, however, considering the hardware image-compositing mechanism in the Radeon X1900 XT CrossFire configuration.

ATI’s multi-GPU technology implemented in senior Radeons seems to depend on the PCI Express bandwidth less than Nvidia’s SLI does. Note also that the performance of the Radeon X1900 XT CrossFire configugation is high enough for playing in 1280x1024 resolution with turned-on 14x Super AA.

Doom 3

The newer chipset brings about a performance growth of 2-3fps in Doom 3 , but only in the 4x FSAA mode. In the other cases the two platforms from ATI Technologies have identical results. The 8x Super AA mode is available here for owners of a Radeon X1900 CrossFire system while the 14x Supper AA mode is not due to low average performance.
