That’s the system that really might blow us all away, but it wasn’t available for review at press time.) Adding it all up (The Power Mac Quad, by contrast, has two processors with a dual core each, or four processing engines in all-twice as many as any previous Mac. OS X apparently doesn’t see much difference: Apple’s System Profiler reports two CPUs, just as in dual-processor systems, and the Activity Monitor works the same way with two cores as it does with two processors.

Put simply, G5s with one dual-core processor replace G5s with two single-core processors in the new dual-core models, even the clock speeds are the same.


The difference is that this benefit used to require two separate, complete CPUs now, with dual-core processors, Apple can include two brains on just one chip.
