The Intel Core i9-11900K is a desktop processor with 8 cores, launched in March 2021. It is part of the Core i9 lineup, using the Rocket Lake-S architecture with Socket 1200. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 16 threads. Core i9-11900K has 16MB of L3 cache and operates at 3.5 GHz by default, but can boost up to 5.3 GHz, depending on the workload. Intel is making the Core i9-11900K on a 14 nm production node, the transistor count is unknown. You may freely adjust the unlocked multiplier on Core i9-11900K, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 125 W, the Core i9-11900K consumes a lot of power, so good cooling is definitely needed. Intel's processor supports DDR4 memory with adual-channel interface. The highest officially supported memory speed is 3200 MHz, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, Core i9-11900K uses a PCI-Express Gen 4 connection. This processor features the UHD Graphics 750 integrated graphics solution.
Hardware virtualization is available on the Core i9-11900K, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512.
