The results for 9800XT, 9600XT and FX 5700 Ultra are unchanged from the 9600XT review, so it's no surprise to see FX 5700 Ultra best its mid-range rival yet again. Superior memory bandwidth helps at all test points, especially as IQ is applied and the pixel count gets rough.

What's interesting and not apparent from the graph, is that the FX 5900 Ultra (ASUS) clocked at 475/950 (FX 5950 Ultra) speeds was the fastest NVIDIA board in the tests. You'll see that throughout the graphs, with the clocked NV35 beating its NV38 stablemate nearly every single time. It seems that memory latencies used on the GDDR2 modules on the NV38 board are slacker than the latencies used on ASUS' FX 5900 Ultra, allowing it a performance advantage at the same clocks.

9800XT runs out the winner at the test setting that matters most, 1024x768x32 with 4xAA and 8xAF.

Notes

I'll use this little notes section at the bottom of each benchmark page to talk about image quality and render issues that may have cropped up. Using 52.16 for the NV36 gives comparatively poor mip stage filtering on the Dragothic low detail test when no texture filtering is applied, alluding to discovery of NVIDIA's apparently less than stellar trilinear filter in these new drivers, but with AF applied, that seems to disappear.
