Core i5-540M is a 64-bit x86 dual-core mobile microprocessor introduced by Intel in 2010. This processor, which is based on the Westmere microarchitecture (Arrandale core), is manufactured on a 32 nm process. This MPU operates at a base frequency of 2.53 GHz with a Turbo Boost frequency of 3.07 GHz and a TDP of 35 W. This processor incorporated the HD Graphics (Ironlake) IGP on the same package operating at a base frequency of 500.00 MHz and a burst frequency of 766.00 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.
