Core i7-6660U is a 64-bit dual-core high-end performance x86 mobile microprocessor introduced by Intel in early 2016. Fabricated on a 14 nm process based on the Skylake microarchitecture, this processor operates at 2.4 GHz with a turbo boost of up to 3.4 GHz. The i7-6660U has a TDP of 15 W with a configurable TDP-down of 9.5 W. This chip incorporates the Iris Graphics 540 GPU operating at 300 MHz with a burst frequency of 1.05 GHz. This processor supports up to 32 GiB of non-ECC dual-channel DDR4-2133 memory. The 6660U comes with an additional 64 MiB of embedded DRAM side cache.

Cache[edit]

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.
