Template:mpu Core i7-640M 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 2.8 GHz with a turbo frequency of 3.46 GHz and a TDP of 35 W. This MPU came with a HD Graphics (Ironlake) IGP operating at 500 MHz with a max burst frequency of 766 MHz.

Cache

Main article: Westmere § Cache

[Edit/Modify Cache Info]

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.
