right now how fast will x86 be running when these PPC chips come out? Some where at 6 to 10GHZ? Maybe more?
I doubt it. 3GHz is quite a significant heat barrier so far for x86, and modern x86 3GHz chips have enormous coolers and fans just to stay running. Unless Intel and AMD do something about this heat problem, a 6GHz CPU will need a small refridgeration unit at about 300W to run. Not what I want for a home computer.
