Exactly. The majority of computing tasks depend on integer
performance, not floating point.
IMHO, it's really too bad the G5 stole the show, because I think the G4
is a better all-around PowerPC cpu. The G5 is nothing but a stripped
down Power4 server cpu. And typically, just like it did in the past
with the Pentium Pro line, server cpu's don't make good all-around
desktop cpu's.
Again, that's why I think engineering resources would be much better
spent on a dual-core G4 PowerBook, rather than a G5. The dual-core
G4's are already there, reportedly running at 2.0 GHz with a ~600 Mhz
frontside bus, and very low power dissipation (something like 15 watts
per core). Somebody just has to weld one to the logic board in a
PowerBook to make it happen.
