Call of Duty 2

The PowerColor X1800 GTO is less than 5fps behind the GeForce 7600 GT in 1024x768. Unfortunately, graphics cards of this class cannot ensure a playable frame rate in this game in higher resolutions – you can only have it with more advanced devices like Radeon X1900 XT or GeForce 7900 GT.

Both the mentioned mainstream solutions yield an average frame rate of less than 50fps in 1024x768 in the “eye candy” mode. And then a strange thing happens: notwithstanding its 256-bit memory bus, the ATI solution is suddenly behind the GeForce 7600 GT! Moreover, the PowerColor X1800 GTO is exactly as fast as the Radeon X1800 XL in 1600x1200 although the two have a different number of execution units, TMUs and ROPs. So it’s not about the GPU, but probably about how the graphics memory is managed by the Catalyst driver.
