Performance in Semi-Synthetic Benchmarks

Final Fantasy XI Official Benchmark 3

The PX6800 GT is slower than the other participating cards even at the overclocked frequencies. This benchmark seems to like high graphics memory speed which all modern RADEONs have.

The Leadtek is no slower than the RADEON X800 XL at the default frequencies and competes with the RADEON X850 XT Platinum Edition at the overclocked ones.

Everything is quite different in the “eye candy” mode: the load on the graphics memory subsystem is multiplied when full-screen anti-aliasing is in use, and the GeForce 6 cards cannot compete with ATI’s cards anymore. Even overclocked, WinFast PX6800 GT is about 5-9% slower than the RADEON X800 XL.
