Below you can see all three scores, namely memory, CPU and total. Looking at the CPU score, which interests us more, the XE6800 is 22.02% faster than the E6600 and 50,23% faster than D930.

There's no real change in the order with the PC Mark 05 tests, and you wouldn't expect there to be. What is surprising though, in a nice way, is how much of a difference the Core 2 Duo processors make in the memory tests.

3DMark®06 is the worldwide standard in advanced 3D game performance benchmarking. A fundamental tool for every company in the PC industry as well as PC users and gamers, 3DMark06 uses advanced real-time 3D game workloads to measure PC performance using a suite of DirectX 9 3D graphics tests, CPU tests, and 3D feature tests. 3DMark06 tests include all new HDR/SM3.0 graphics tests, SM2.0 graphics tests, AI and physics driven single and multiple cores or processor CPU tests and a collection of comprehensive feature tests to reliably measure next generation gaming performance today.

Below we find both the CPU and total scores, where again the XE6800 is fastest.
