Template:mpu Core i7-7660U is a 64-bit dual-core high-end performance x86 mobile microprocessor introduced by Intel in early 2017. This processor, which is based on the Kaby Lake microarchitecture, is manufactured on Intel's improved 14nm+ process. The i7-7660U operates at 2.5 GHz with a TDP of 15 W and with a Turbo Boost frequency of 3.5 GHz for a single active core. This MPU supports up to 32 GiB of dual-channel non-ECC DDR4-2133 memory and incorporates Intel's Iris Plus Graphics 640 IGP operating at 300 MHz with a burst frequency of 1.1 GHz. This particular GPU includes an additional 64 MiB of eDRAM L4$.

[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.
