RADEON X1600 XT performs surprisingly well here even despite the inefficient OpenGL driver and too few TMUs. At least it is up to 50% faster than RADEON X800 XL in high resolutions in pure speed mode. Maybe that’s because Pacific Fighters supports Shader Model 3.0 and ATI’s new solution outperforms the previous generation ones, which support only Shader Model 2.0. In 1600x1200 RADEON X1600 XT comes up real close to GeForce 6600 GT thanks to its new memory controller.
In eye candy mode with full-screen anti-aliasing RADEON X800 XL with 32GB/s memory bandwidth starts to surpass RADEON X1600 XT with its 22.08GB/s. Unfortunately, both ATI solutions can ensure minimum comfortable gaming performance with enabled FSAA only in 1024x768, while GeForce 6800 allows you to play just fine in 1280x1024. Again, they should blame the inefficient ATI OpenGL driver for that.
