Core i7-8086K is a 64-bit hexa-core high-end performance commemorative x86 desktop microprocessor introduced by Intel on the 40th anniversary of the 8086. This processor, which is based on the Coffee Lake microarchitecture, is manufactured on Intel's 3rd generation enhanced 14nm++ process. The i7-8086K operates at a 4 GHz with a TDP of 95 W and a Turbo Boost frequency of up to 5 GHz. This chip supports up to 64 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.

Overview

Launched by Intel on June 8 2018, this processor was first suggested by WikiChip as a celebratory chip for the 40th anniversary of the original 8086 which debut on June 8, 1978. The i7-8086K is a direct descendant of Intel's original 8086, capable of executing original 8086 code in real mode. Originally operating at a frequency of 5 MHz, the new commemorative i7-8086K has a turbo boost frequency x1000 faster at 5 GHz.

At 5 GHz turbo, the Core i7-8086K is Intel's highest frequency consumer processor ever released, and is tied with AMD's FX-9590 as the fastest consumer processor ever made, as of late 2018. (in terms of frequency not performance)

Box

The chip itself comes in a special "limited edition" box along with a commemorative card and a certificate of authenticity.

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.
