Product overview

Released April 5, 2022, the Core i9-12900KS is a 12th‑Gen Alder Lake special‑edition desktop CPU on Intel 7 with 16 cores (8P+8E) and 24 threads. It targets Intel’s LGA1700 platform and 600‑series motherboards, includes Intel UHD Graphics 770, and boosts up to 5.5 GHz via Intel Thermal Velocity Boost.

Positioned as Intel’s flagship SKU of its generation, it exists for builders who want the fastest stock‑clock Alder Lake chip. It’s well‑suited to 1440p and 4K gaming, plus streaming and heavy creation work such as video editing and 3D rendering. Unique note: this KS is a binned, unlocked‑multiplier variant of the 12900K with higher boost ceilings. Intel has discontinued the 12900KS; last orders were January 24, 2025, with final shipments by July 25, 2025.
