Core i7-8700K - Intel

Core i7-8700K is a 64-bit hexa-core high-end performance x86 desktop microprocessor introduced by Intel in 2017. This processor, which is based on the Coffee Lake microarchitecture, is manufactured on Intel's 3rd generation enhanced 14nm++ process. The i7-8700K operates at a 3.7 GHz with a TDP of 95 W and a Turbo Boost frequency of up to 4.7 GHz. This chip supports up to 128 GiB of dual-channel DDR4-2666 memory and incorporates Intel's UHD Graphics 630 IGP operating at 350 MHz with a burst frequency of 1.2 GHz.

The Core i7-8700K is Intel's flagship mainstream processor based on Coffee Lake, succeeding the Core i7-7700K.

Cache[edit]

[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.
