Real World? P4 and Athlon are much faster than any current Mac by more than 2-3 times. I read several articles comparing a P4 2.5 Ghz against a double 1Ghz processor mac, and Mac didn't even come close...as in, it was half the speed. But I do hope this new line kicks Intel and Athlon butt.
You cant put the two up against each other on clock speed, they are not the same at all. PPC is much faster with the same clock speed as a X86 chip.
