The Intel Core i9-12900KS is a desktop processor with 16 cores, launched in April 2022. 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 i9-12900KS has 30MB of L3 cache and operates at 3.4 GHz by default, but can boost up to 5.5 GHz, depending on the workload. Intel is making the Core i9-12900KS on a 10 nm production node, the transistor count is unknown. You may freely adjust the unlocked multiplier on Core i9-12900KS, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency. With a TDP of 150 W, the Core i9-12900KS is extremely power hungry, which means you need top-notch cooling. Intel's processor supports DDR4 and DDR5 memory with adual-channel interface. For communication with other components in the computer, Core i9-12900KS uses a PCI-Express Gen 5 connection. This processor features the UHD Graphics 770 integrated graphics solution. Hardware virtualization is available on the Core i9-12900KS, 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.
