Core i7-640LM is a 64-bit dual-core x86-64 mobile microprocessor designed by Intel and introduced in early 2010. This chip is a first-generation Core i7 processor based on the Westmere microarchitecture and is manufactured on a 32 nm process. This processor operated at a based frequency of 2.13 GHz with a turbo frequency of 2.93 GHz and a TDP of 25 W. This MPU came with a HD Graphics (Ironlake) IGP operating at 266 MHz with a max burst frequency of 566 MHz.

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
