Intel’s new Xeon 5500 series - Nehalem' architecture

Intel’s new Xeon 5500 series uses the chip giant's 'Nehalem' architecture to effectively put a pair of Core i7 CPUs on a workstation motherboard. but at the same time Apple had launched a new Mac pro and it's architecture is different from previous launch.
