[X4U] 64 vs 32 was...Re: move to Intel

[Richard Gilmore]

The memory's the same, DDR PC 3200, granted the iMac bus is faster 600 vs
166 on the mini, L2 cache is the same, don't know about GPU etc...(will
investigate) but to my mind that doesn't seem enough to account for huge
difference in performance. If the bus/GPU etc...is all that's making the G5
faster why put a new expensive chip in there in the first place? From a
business point of view the profit margin would be much greater by simply
using a cheaper G4 chip and not redesigning the whole machine around a new
chip and architecture that's only 380MHZ faster. Why reinvent the wheel? I'm
not a computer engineer but a 64 bit processor actually being slower than a
32 doesn't make sense to me and contradicts my anecdotal evidence that the
G5 is substantially faster. Have I had the wool pulled over my eyes by
Apple?
