The top performing Core i7 600LM, low voltage mobile CPU scheduled to launch in Q4 2010 will work at 2.26GHz. If this is not enough from this dual-core Arrandale 32nm-based CPU with 45nm graphics, with a little help from Intel's Turbo it will boost its clock all the way over the magic 3GHz mark, to 3.06GHz to be percise. Its graphics will work at 266MHz when you don’t need much graphics power, but the core will increase its clock to 566MHz when you put it under lot of pressure.

The DDR3 memory of this CPU works at 1066MHz and the CPU has 4MB cache memory. It runs with 25W TDP which is just seven watts more than Core i7 6x0UM series that runs at speeds between 1.06GHz and 1.46GHz.

Intel is still struggling to ship any of its ultra-low voltage CPUs and we still have to see some Core i7 ULV and LV CPUs shipping in fancy new notebooks. The first Core i7 640LM should ship in Q2 2010, the current quarter, and the 660LM will just be a faster iteration of the same concept and TDP, coming in Q4 2010.
