'''Core i7-640UM''' is a {{arch|64}} [[dual-core]] [[x86-64]] mobile microprocessor designed by [[Intel]] and introduced in early [[2010]]. This chip is a first-generation {{intel|Core i7}} processor based on the {{intel|Westmere|l=arch}} microarchitecture and is manufactured on a [[32 nm process]]. This processor operated at a based frequency of 1.2 GHz with a {{intel|Turbo Boost Technology|turbo frequency}} of 2.27 GHz and a TDP of 18 W. This MPU came with a {{intel|HD Graphics (Ironlake)}} [[IGP]] operating at 166 MHz with a max burst frequency of 500 MHz. This model is part of the [[part of::Ultra-Low Power]] series.
