Intel · Core i9 · 2019 · LGA1151
The Intel Core i9-9900KS is a desktop processor with 8 cores, released in 2019. 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 i9-9900KS has a base clock of 4 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 127W, the Core i9-9900KS sits in a typical power envelope for a modern desktop CPU. Integrated graphics are provided by the UHD 630 solution, so a discrete GPU is not required for display output. The cache hierarchy consists of 32KB/core of L1, 2MB of L2, and 16MB of L3 cache.
Special-edition KS part with up to 5.0 GHz boost.
