A newly escaped Intel roadmap has confirmed that the chip designer is planning a sweeping upgrade to its notebook processors in the fall beyond what has been seen so far. Along with the 2.66GHz Core i5 580M, Intel would upgrade the higher end of its dual-core chips with a 2.8GHz Core i7 640M. The replacement for the 2.66GHz i7 620M would Turbo Boost to 3.46GHz and still use the same 35W of power, rendering it a drop-in upgrade for thin notebooks such as the MacBook Pro.
