Product identity
The Intel Core i9-12900KF is a 16-core desktop processor built on the Alder Lake architecture. It combines eight performance cores and eight efficient cores to deliver 24 threads for demanding workloads. The chip fits the LGA 1700 socket and operates with a base power of 125 watts.
Hybrid core configuration
Eight performance cores run at a 3.2 GHz base frequency and can reach up to 5.2 GHz with Intel Turbo Boost Max Technology 3.0. Eight efficient cores operate at a 2.4 GHz base and boost to 3.9 GHz. The design provides 30 MB of L3 cache and 14 MB of L2 cache to keep data close to the cores.
Thermals and power
Processor base power is rated at 125 watts while maximum turbo power can reach 241 watts under heavy loads. No cooling device is included in the package so a suitable solution must be provided separately. The 10 nm manufacturing process helps manage heat density across the hybrid core layout.
