An unofficial report has Intel releasing a new ultra-low voltage Core i7 CPU this summer, the 660UM. The dual-core chip would produce a 1.33GHz clock speed but ramp up to 2.4GHz speeds when overclocked in Turbo Boost. When it arrives, it should supercede the 1.2GHz Core i7 640UM, support the same 800MHz DDR3 memory and consume the same 18W of total power as the slower model.
