Unreal Tournament 2003 Botmatch
In the Botmatch test, a heavy load is put on the CPU. However, the graphics card also has more on its hands with additional objects (the figures) and effects (gunfire, explosions). Here, the Radeon and the FX are nearly neck-on-neck. It's only in 1600x1200 that the FX manages to pull ahead.
The above graphic was created with Utility UTBench v1.32. Further information about this program can be found here: Ben's Custom Cases . The identical settings were used at a resolution of 1280x1024. The result shows a progressive curve in the benchmark in Antalus Flyby. The curves were brought into a single image using an image editor.
