I've looked at "mac.com" and what I've seen is lies, evasion, and deliberate distortion by a company attempting to deceive in order to cover up the fact that their machines are distinctly behind the curve, overpriced and horribly underpowered, because their main supplier of processors isn't staying competitive. I see a company attempting to convince the gullible that up is down, sideways is straight ahead, and the G4 is always faster than the P4 no matter what their relative clock rates. <br

By the way, here's an interesting fact. When any pipelined processor mispredicts a branch, it has to flush its pipeline and refill it. Most processors now are very good at branch prediction, and both the Athlon and P4 predict correctly more than 90% of the time (though I don't know the exact figure, and note that it varies depending on the program). The G4 has to, also. When the G4 mispredicts, it has to reload all 7 pipeline stages, taking 7 clock cycles to do so. Assuming a 1 GHz cloc
