Intel Xeon CPU featuring six cores, and currently known as Gulftown should arrive during H2 2010. Those CPU should be compatible with the motherboard currently used to host Xeon Nehalem in the Mac Pro 2009. The TDP should be maintain below 130 W thanks to 32-nm engraving process while being compatible with the current cooling system. With such future generation planned more than year after the last update of the Mac Pro, Apple will most likely make the Mac Pro design/offer evolving when the Gulftown will become available.
