Template:mpu Core i7-8550U is a 64-bit quad-core performance x86 mobile microprocessor set to be introduced by Intel in mid-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 ? GHz with a TDP of 15 W and with a Turbo Boost frequency of ? GHz for a single active core. This MPU supports up to 32 GiB of dual-channel non-ECC DDR4-2133 memory.

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.
