Intel today unveiled its second wave of 32nm notebook processors today with updates to its Core i5 and Core i7 lines.
Updates are as follows: the Core i7 640M upgrades to 2.8GHz (from 2.66GHz) for $349 in bulk; the Core i5 580M moves the top i5 chip to 2.66GHz (from 2.53GHz) for $266, and the slightly detuned but same-speed Core i5 560M costs $225. All models have Turbo Boost.
Low- and ultra-low voltage processors also have upgrades upgrades. The new 2.26GHz Core i7 660LM costs $346. Ultra low voltage models for ultraportables top out at the 1.46GHz Core i7 680UM ($317) and also include the 1.33GHz i5 560UM ($250).
Core i5 and i7 notebook models are separated only by cache, as i7 models have 4MB of Level 2 cache while i5 versions are pared down to 3MB.
Two Celeron models, the P4600 and T3500, are available and cost $86 and $80.
Computer builders are expected to start using the faster processors almost immediately.
