The Core i9-12900KS is Intel's fastest Alder Lake desktop chip: 16 cores (8 performance, 8 efficiency), 24 threads, and a 5.5 GHz top boost out of the box. It is a pre-binned, factory-overclocked take on the i9-12900K, so it runs hotter and draws more power than the standard part. It suits high-refresh gamers and heavy multitaskers on LGA 1700 who want top-tier performance without moving to a newer platform. Reviewers rate its speed highly but note the heat, power draw and modest gain over the 12900K.
