Template:mpu Core i7-8850H is a 64-bit hexa-core high-end performance x86 mobile microprocessor set to be introduced by Intel in 2018. This processor, which is based on the Coffee Lake microarchitecture, is manufactured on Intel's 3rd generation enhanced 14nm++ process.

- Main article: Coffee Lake § Cache
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. |
