tenang aja, komentar yang dulu2 juga masih tetep ada:
"Rather than being just 35% faster, the new Power Mac G4 is up to a
stunning 100% to 200% faster
than the fastest Pentium III-based PCs."
komentar John Carmack:
The initial systems are just G4 processors in basically the same systems as
the current G3. There will be some speedup in the normal C code from the
faster floating point unit, and the Apple OpenGL has AltiVec optimizations,
so framerates will improve somewhat. The limiting factor is going to be
the fill rate on the rage128 and the bandwidth of the 66mhz pci bus and
processor to main memory writes.

On a purely technical note, AltiVec is more flexible for computation than
intel or AMD's extensions (trinary ops), but intel style write combining is
better for filling command buffers than the G4's memory streaming operations.
