Bare Feats has posted various test results comparing “CPU Crunching” for a Dual G5/2.5GHz Power Mac vs. Dual G5/2.0GHz Power Mac vs. Dual Xeon 3.4GHz vs. Pentium 4 3GHz vs. 64 bit Athlon 2.2GHz = 3GB of 333MHz DDR which shows that the top G5 Power Mac (dual 2.5GHz) won every CPU intensive test except one.
Test results here.
Bare Feats explains, “Though the G5 Power Macs did well in the CPU tests, they were pretty much ‘smoked’ in the 3D GRAPHICS tests. Part of it as to do with how much effort developers put into optimizing (or re-writing) the game code to take advantage of the unique features of the G5 Power Macs. Quake 3 Arena, though considered obsolete by avid gamers, is a perfect example of the potential of the G5 Power Macs to excel in gaming.”
