There is a big difference in archetecture between the G4 and P4. See...Mhz is the number of cycles (how quickly something can get pushed through) which Intel has that. The difference is that G4s are much more effecient, processing 128 bits of info per cycle (with the velocity-engine) vs. the P4's 64 bit processing. The thing is that if an operation only requires 32 or 64 bits at a time to complete, P4 has the high advantage because that has taken up one cycle and not used 64 bits of capability, but if it is a processor intensive task such as graphics, a G4 will do much more in one cycle (effectively doubling the processor's speed). There are other factors to figure in such as the number of instructions built into the processor which help the processor more efficently process (G4 has the advantage here, too). Apple's G4 processors are 2.2Ghz only when matched with a P4 on a 128 bit cycle for the P4 has to break up the cycle. On easier, less processor intensive tasks like gaming and casual usage, the P4 has the noticeable advantage. The P4 will preform better on the required graphics acceleration of WinXP window moving and resizing than the G4 on OSX and the P4 will be able to provide less staggering of some applications while others are in operation.
I am sorry if I am not the most clear on this...it is 3:30AM and I am about to pass out....have fun and I hope I have at least somewhat enlightened some of you. If you want more clarity...e-mail me at Arthur_bogard@hotmail.com
