The Intel Core i9-9900KF is a desktop processor with 8 cores, released in 2019 at an MSRP of $488. It is part of the Core i9 lineup, using the 9th Gen platform, and fits the LGA1151 socket. Internally, it is built on the "Coffee Lake Refresh" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 16 threads for improved parallelism. The Core i9-9900KF has a base clock of 3.6 GHz and can boost up to 5 GHz depending on workload and thermal headroom. Intel manufactures the "Coffee Lake Refresh" silicon on a 14nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR4 memory. With a TDP of 95W, the Core i9-9900KF sits in a typical power envelope for a modern desktop CPU. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 32KB/core of L1, 2MB of L2, and 16MB of L3 cache.
KF variant — no integrated graphics. Otherwise identical to i9-9900K.
