[X4U] New iMacs vs. Mac Pro (processor, performance)

[Jon Kreisler]

One thing to remember about Apple and GHz ratings...
When Apple quotes a processor clock speed, they are giving you "guaranteed"
clock rating based on
their testing of the chipset. If it is indeed the 2.93 Intel Core 2 Extreme
Processor X6800, it just may be that Apple determined, in a Mac, there were
too many instances where the chip didn't perform reliably above 2.8 GHz, so
they rated the Mac at 2.8 GHz, because it can consistently run at 2.8 or
better.
