The results show that the Intel system was the fastest in every respect, and that was at standard speeds when you can be sure that the 2.4GHz CPU will overclock past 3GHz with the minimum of effort. The Core 2 Quad did better than Athlon 64 and Phenom in the synthetic system PCMark05 test but in POV-Ray 3.7 the Intel processor completely eclipsed the AMD contenders.
