Core i7-640M is a dual-core microprocessor from a Core i7 Mobile family of high-performance CPUs. First references to this model appeared in May 2010 in a leaked Intel roadmap. Preliminary price for the CPU was published at the end of June, and the first notebooks with the CPU were spotted in July. The CPU was released in September 2010 as part of a big launch of standard-, low- and ultra-low mobile Arrandale models, including Core i7-680UM, Core i5-460M / i5-560M / i5-560UM / i5-580M, Core i3-380M, Pentium P6100 / P6200, and Celeron P4600.

Core i7-640M is based on Arrandale core, which in turn is built 32nm Westmere micro-architecture. The Arrandale core combines two dies in one package: one die with two HyperThreading-enabled cores and a shared 4 MB level 3 cache, and another die with DDR3 memory controller and 500 MHz graphics controller. Each core in the i7-640M is clocked at 2.8 GHz, and has 256 KB L2 cache. The microprocessor supports all basic and advanced Arrandale features, like 64-bit instructions, SSE4, AES instructions, Trusted Execution Technology and Turbo Boost. The last feature improves CPU performance by increasing frequency of active cores. Maximum Turbo Boost frequency on this model is 3.46 GHz. The processor is produced in socket 988-compatible micro-PGA package. There is also a version of i7-640M model for micro-BGA package.

Before the launch, the Core i7-640M was sighted in specifications of Fujitsu LIFEBOOK S710, S760, NH570, E780 notebooks, Fujitsu LIFEBOOK T900 tablet PC, and HP ProBook 4520s and 4720s laptops.
