Call of Duty, Serious Sam: Second Encounter, UT2003
Call of Duty
In Call of Duty, our first OpenGL test, the PRO as equivalent to the 5900 PCX, with the XT shadowing the 6600 GT. The 6600 GT has a driver bug in this test at 1600x1200. The 6800 GT is CPU limited quite heavily initially, so you get 4x AA and 8x AF for free on that board in Call of Duty, at 1024x768.
Serious Sam: Second Encounter
Serious Sam is our second OpenGL test and it's very multi-texture heavy (applying up to four textures in a render pass). The Radeon X700 boards have a hard time here, compared to the mid-range NVIDIA boards. The XT is some 10-20% faster than the PRO depending on setting, both boards falling well short of the pace set by the 6600 GT.
UT2003
The PRO is slower than 5900 PCX in our UT2003 test. NV35 always was pretty happy rendering UT2003 and it shows here. Its texel fillrate is high due to two texture samplers per pipe and it has masses of memory bandwidth compared to the PRO, helping things along. XT #1 = XT #2, and both fight the 6600 GT for the mid-range enthusiast spoils. Neither wins, rather both gang up give UT2003 a kicking and move on to something more challenging.
