We'd say Intel is delivering its new chips like clockwork, but then our favorite timepieces don't usually leak anywhere near as often as Chipzilla's roadmaps. The now well known 2.66GHz Core i5-580M has finally been made official, costing $266, alongside an identically clocked family mate in the Core i5-560M, which will set bulk buyers back $225 a piece. From what we know of those two, the major difference is that the 580M can Turbo Boost its way to 3.33GHz whereas the 560M maxes out at a humbler 3.2GHz. Both are overshadowed, however, by the new i7-640M colossus, which runs at 2.8GHz by default and will reach 3.4GHz when called upon -- yours for only $346. Of course, should the 35W TDPs of those chips seem too gaudy for you, Intel's wisely dropping a pair of 18W parts as well: the Core i5-560UM slinks along at 1.33GHz and asks for $250, while the Core i7-680UM raises those numbers to 1.46GHz and $317, respectively. Finally, for the perfect balance of power and efficiency, the i7-660LM couples 2.26GHz (or 3.06GHz in Turbo mode) to a 25W thermal envelope. It matches the 640M with a $346 unit price. All these CPUs sport a pair of 32nm cores alongside a 45nm integrated graphics unit and there are absolutely no Performance Upgrade Card anywhere in sight!
