[CUBE] OT: pismo vs ibook

[Robert Jagitsch]

Even if G4 500 was faster on Altivec by some degree, unless your 
needs are extremely specialized you probably won't use Altivec more 
than say 5% of the time. The faster clock speed 95% of the time is a 
much more substantial factor in overall performance. You'd have to be 
running Photoshop filters that utilize Altivec virtually all the 
time. And in our tests, the faster clock speed more than makes up for 
Altivec because the Altivec unit is running at 5/9th the speed (not 
to mention the L2 cache running at 2/9th.)
