Core i7-8550U is a 64-bit quad-core performance x86 mobile microprocessor set to be introduced by Intel in late 2017. This processor, which is based on the Coffee Lake microarchitecture, is manufactured on Intel's 3rd generation enhanced 14nm++ process. The i7-8550U operates at 1.8 GHz with a TDP of 15 W and with a Turbo Boost frequency of 4.0 GHz for a single active core. This MPU supports up to 32 GiB of dual-channel non-ECC DDR4-2133 memory.

[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.
