Coffee Lake is Intel's codename for its eighth-generation Core microprocessor family, announced on September 25, 2017.[5] It is manufactured using Intel's second 14 nm process node refinement.[6] Desktop Coffee Lake processors introduced i5 and i7 CPUs featuring six cores (along with hyper-threading in the case of the latter) and Core i3 CPUs with four cores and no hyperthreading.
On October 8, 2018, Intel announced what it branded its ninth generation of Core processors, the Coffee Lake Refresh family.[7] To avoid running into thermal problems at high clock speeds, Intel soldered the integrated heat spreader (IHS) to the CPU die instead of using thermal paste as on the Coffee Lake processors.[8] The generation was defined by another increase of core counts.
Coffee Lake is used with the 300-series chipset, and officially does not work with the 100- and 200-series chipset motherboards. Although desktop Coffee Lake processors use the same physical LGA 1151 socket as Skylake and Kaby Lake, the pinout is electrically incompatible with these older processors and motherboards.[9]
On April 2, 2018, Intel released additional desktop Core i3, i5, i7, Pentium Gold, Celeron CPUs, the first six-core Core i7 and i9 mobile CPUs, hyper-threaded four-core Core i5 mobile CPUs, and the first Coffee Lake ultra-power CPUs with Intel Iris Plus graphics.
On June 8, 2018, to commemorate the 40th anniversary of the Intel 8086 CPU architecture, Intel released the i7-8086K as a limited edition CPU, a renumbered and slightly higher clocked batch of the i7-8700K dies.
