Asus A8R32-MVP Deluxe: ATI CrossFire Xpress 3200 Chipset Launched
CrossFire Super AA Performance
For our last set of benchmarks, we tested all of ATI's Super AA modes using a pair of Radeon X1900 cards running in a multi-GPU CrossFire configuration. We ran the same set of tests on the CrossFire Xpress 3200 and on the Radeon Xpress 200 to see if the increased graphics bandwidth offered by the CrossFire Xpress 3200 chipset had a measurable impact on framerates in a couple of popular games. The tests below were run with each game set to its highest quality modes at a resolution of 1280x1024.
Interestingly enough, running the same pair of graphics cards, with the same CPU and RAM, on the CrossFire Xpress 3200 based Asus A8R32-MVP motherboard resulted in higher framerates across the board (pun intended), versus the Radeon Xpress 200 based ECS KA1-MVP. It's hard to say whether the chipset by itself, or a the cumulative effect of all of the differences between the motherboards caused the performance increases we see here, but the CrossFire Xpress 3200 did offer the best performance, sometimes outpacing the Radeon Xpress 200 by as much as 5%.
