Unreal Tournament is the first 3D-game example that does not favor Pentium 4. Here Athlon is clearly ahead of the Intel flagship processor.
The higher screen resolution doesn't change the picture much. Athlon 1200 is already able to beat the new Pentium 4 1.7 GHz.
This DirectX 7 game can produce quite a high workload for graphics cards as well as CPUs.
Once more Pentium 4 1.7 is not even able to reach Athlon 1200 scores. This game shows that Pentium 4 is far from being a great gamers processor with today's games. This might finally change though.
Once bump mapping is enabled and the screen resolution is brought up to 1024x768x32, the graphics card is the limiting factor, so that all processors score alike. Keep this phenomenon in mind when you try to choose a processor for your system. At this resolution the graphics card is much more important than the processor.
