You are comparing apples and oranges. Server processors are designed to work in a totally different way to desktop processors. They need to handle many more calculations than a desktop processor, but usually shorter, less demanding calculations. A better comparison to the Istanbul chip would be the also upcoming latest Intel server chip, Nehalem-EX, due out very soon.Nehalem-EX is based on the same architecture as the Core i7 and the Xeon 5500 series, but it's been pumped up to the max. It has eight cores, 16 threads, 24MB shared cache, four memory channels, four QuickPath links, and supports up to 16 memory modules per socket (with the help of memory buffer chips on the motherboard).
