The Intel Core i9-12900K is a desktop processor with 16 cores, launched in November 2021. It is part of the Core i9 lineup, using the Alder Lake-S architecture with Socket 1700. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 24 threads. Core i9-12900K has 30MB of L3 cache and operates at 3.2 GHz by default, but can boost up to 5.2 GHz, depending on the workload. Intel is building the Core i9-12900K on a 10 nm production process, the transistor count is unknown. You may freely adjust the unlocked multiplier on Core i9-12900K, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 125 W, the Core i9-12900K 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 computer, Core i9-12900K uses a PCI-Express Gen 4 connection. This processor features the UHD Graphics 770 integrated graphics solution.
Hardware virtualization is available on the Core i9-12900K, 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) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel has added support for the newer AVX2 and AVX-512 instructions, too.
