writes "WWDC is drawing nearer and ArsTechnica has a thorough look at what they think Apple's plans are for their future Pro desktop line. It's a decent read. As always Ars has a competent pulse on Apple and is more reasonable than purely speculative. From the article:
I think Apple's CPU choice is clear cut. Strange as it sounds, the Xeon 5100 series is the best fit for the Mac. If Apple wants to keep the Quad name alive, it's the only option. Dual CPU configurations are not possible with anything else in Intel land, so if Apple wants to offer two CPUs and four cores, Xeon is the only game in town. With the benchmarks we have seen, the Core 2 Duo is a clear winner for Intel, outperforming anything AMD has to offer. The Xeon? With its faster FSB and different memory, it's even faster than the Core 2 Duo."
