Ponder this: Is an Intel product launch still a launch, if the product debuts very publicly in an Apple computer?
I won't presume to answer that question. But the fact is that Intel will launch Nehalem-EP server processors later this month, despite their manifestation Tuesday in the new Mac Pro under their official model names: the Xeon 3500 and 5500.
The chips--in their desktop variant known as the Core i7--are being offered in eight-core or four-core configurations and, like all Nehalam-architecture processors, come with an integrated memory controller for (theoretically) better performance. (Intel's Core architecture does not integrate the memory controller.)
Other Nehalem-architecture features include: Hyper-Threading for, according to Apple, "up to 16 virtual cores" (which improves multitasking), and Turbo Boost Technology, which dynamically increases the processor's frequency, as needed.
