Core i5-6440HQ is a 64-bit quad-core x86 mid-range performance mobile microprocessor introduced by Intel in late 2015. The i5-6440HQ, which is based on the Skylake microarchitecture and is fabricated on a 14 nm process, has a base frequency of 2.6 GHz and a turbo boost frequency of up to 3.5 GHz with a TDP of 45 W and a configurable TDP-down of 35 W. This processor incorporates the HD Graphics 530 integrated graphics operating at 350 MHz with a turbo frequency of 950 MHz. This model supports 64 GiB of dual-channel DDR4-2133 memory.

Cache

Main article: Skylake § 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.
