Reported a couple of times altready, Intel now has ofiically added three new IGP-less Core i5 processors to its official price list.
The chips come with their GPUs disabled and can be identified by the model numbers 2550K, 2450P, and 2380P. That first CPU features a fully unlocked upper multiplier, so it's the one you'll want.
Versus the existing Core i5-2500K, the 2550K offers 100MHz increases in base and Turbo frequencies, bringing the chip up to 3.4GHz with a 3.8GHz Turbo peak. Those speeds match the Core i7-2600K, which offers additional cache and Hyper-Threading support missing from the i5 series. Intel is selling the 2550K at $225
