List of Intel Core i9 processors

The following is a list of Intel Core i9 brand microprocessors. They were introduced in May 2017.^[1]^[2]^[3] With their high number of cores, high power draw, high thermal output, high performance, and unique desktop socket, LGA 2066, they are intended to be used by enthusiasts. A mobile version based on the standard BGA1440 socket was released in 2018, featuring six hyperthreaded cores and 12 MB of cache. It has been proven to attain 5 gigahertz under ideal conditions.^[4] It is rumored that the next generation of Intel CPUs will feature the Core i9 9900K, an eight-core hyperthreaded processor, while the Core i7 9700K will also feature eight cores without hyperthreading. Up till the end of 2018, the top-end model have 18 cores.
