Template:mpu Core i3-390M is a 64-bit dual-core x86 mobile microprocessor introduced by Intel in 2010. This processor operates at a frequency of 2.66 GHz and a TDP of 35 W. This MPU is manufactured on a 32 nm process based on the Westmere microarchitecture (Arrandale core). 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 667.00 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.
