there you go AGAIN, confusing software performance with CPU
performance. the apps you refer to were written for the Win/Tel
architecture, and ported to the PPC by lazy and/or incompetent boobs
who wouldn't or couldn't rewrite the program from the ground up in
such a way as to fully exploit the Altivec processor. a 1 gig intel
processor does a billion floating-point operations per second, while a
1 gig PPC does one billion 64-bit vector operations per second. it is
theoretically 64 times faster than an intel CPU with the same clock
speed, but only if you have programmers smart enough and industrious
enough to exploit it's full power. why do you think the DOD still
restricts the sale of G4s and G5s overseas, but you can give north
korea all the intel machines they want.
Theory is all well and good, but it won't trans-code my videos or do
anything else. Unless you are able to roll your own apps that do use the
PPCs abilities efficiently, reality is that a MacPro is faster than a
Power Mac.
