The new Mac Pro is obviously held up by hardware integration issues. One might suspect the Intel set chips are the culprit, but never mind Intel, AMD and its potential of 48 physical cores have provided Apple's difficulties in the final release decisions. While the Intel processors have the been the go-to chips for Apple in the past four years, the skyrocketing prices and lack of supply are creating constraints on the marketplace that haven't been there in the past. With the requirement to submit to consumers wants and needs on the power to price ratio, Apple has been forced to explore the potential of integrating the AMD set chips in lieu of Intel products, as did Sun Microsystems. The rebirth of the new Mac Pro will... ehh emm... most likely include the 8-core and 12-core AMD Opteron 6000 Series chip platform requiring a radical redesign of the Mac Pro chassis. The new chassis might also be the segue for Apple to combine the Mac Pro and the Xserve product lines, as it will make more sense for the Mac Pros to run the server editions of the OS X operating systems, as well as provide the high end customers a factory way to rack mount the computers.
