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!
