The Core i7 640UM mobile dual-core looks like it could be a very impressive mobile CPU that will be launched in the first Quarter of 2010.

It will likely be the main CPU for the ultra-thin, "Ultra-Mobile" (UM) performance market and runs dual cores at 1.2GHz default clocks but with Turbo mode, it can overclock all the way to an astonishing 2.26GHz per core.

All of this can be done in under an 18W TDP envelope which is a great number considering that the integrated graphics core (IGP), integrated memory controller (IMC) and northbridge (IOH) are all part of this 32nm Arrandale-based CPU.

The CPU comes with 4MB of cache, a 1066MHz FSB, and its H55 chipset supports switchable graphics.
