Performance in First Person 3D Shooters
It’s not quite right to compare graphics cards from RADEON X8x0 and GeForce 6800 series in Doom 3 since the game obviously favors the latter. The WinFast PX6800 GT is rather too far ahead of the more advanced and expensive RADEON X850 XT Platinum Edition.
It’s the same story in the “eye candy” mode with enabled full-screen anti-aliasing and anisotropic filtering. Even the advanced memory controller can’t help ATI’s cards here just because the game engine is GeForce-oriented.
The numbers are different on the d3dm4 map, yet the overall picture is the same: the GeForce6 cards triumph over their rivals.
This is the only case in Doom 3 when the ATI RADEON X850 XT Platinum Edition manages to overtake the WinFast PX6800 GT when the latter works at its default frequencies.
