Product overview
Launched on October 8, 2018, the Core i9-9900K is a 9th‑Gen Intel Core (Coffee Lake Refresh) desktop CPU for LGA1151 with 8 cores/16 threads, a 3.60 GHz base and up to 5.00 GHz Turbo Boost 2.0, plus Intel UHD Graphics 630; it pairs with Intel 300‑series motherboards and DDR4‑2666. As an enthusiast‑tier part, it existed to bring top mainstream clocks and an 8C/16T configuration to high‑end gaming and creator builds; the “K” suffix means an unlocked multiplier for overclocking. It’s a strong fit for high‑FPS 1080p/1440p gaming, streaming, and video editing, and it handles office/productivity with ease; the iGPU supports Intel Quick Sync Video for accelerated media tasks. It is now listed as discontinued on Intel ARK.Sourcedownload.intel.comSourceintel.com
