Core i7-8559U is a 64-bit dual-core high-end performance x86 mobile microprocessor introduced by Intel in early 2018. This processor, which is based on the Coffee Lake microarchitecture, is manufactured on Intel's improved 14nm++ process. The i7-8559U operates at 2.7 GHz with a TDP of 28 W and with a Turbo Boost of up to 4.5 GHz. This MPU supports up to 32 GiB of dual-channel DDR4-2400 memory and incorporates Intel's Iris Plus Graphics 640 IGP operating at ? MHz with a burst frequency of ? GHz. This particular GPU includes an additional 64 MiB of eDRAM L4$.

Cache

Main article: Coffee Lake § 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.
