The Intel Core i7-8700K Hexa-Core CPU

The Intel Coffee Lake (8th Gen) processors are built on the same 14 nm process technology as the Intel Skylake and Kaby Lake processors, albeit refined. In addition to the two extra processor cores, it packs a 50% larger L3 cache and support for faster DDR4-2666 memory.

Even with the two additional cores and a larger L3 cache, the Intel Core i7-8700K looks like any other LGA 1151 processor that have come out of Intel’s factories in years past. However, it cannot be used in older Intel 100-series or 200-series motherboards. Even though it uses the same LGA 1151 socket, its pin configuration has changed. It must be installed in an Intel 300-series motherboard.
