The Intel Core i9-12900K is a high end CPU for desktops based on the Alder Lake architecture. It was first announced in November 2021 and offers 8 performance cores and 8 efficiency cores. The performance cores (P-cores) support HyperThreading, leading to 24 Threads that can be processed at once. The performance cores can clock with up to 5.2 GHz (Turbo Boost Max 3.0), the efficiency cores can clock with up to 3.9 GHz. All cores can use 30 MB Smart Cache. The integrated memory controller supports up to 128 GB DDR5 with 4800 MT/s (dual channel).
The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficiency cores for the best performance.
For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (most likely only using AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC and AV1 decode in hardware.
The integrated graphics adapter is based on the Xe architecture and called Intel UHD Graphics 770. It clocks between 300 and 1.55 GHz.
Performance
The average 12900K in our database nearly matches the Ryzen 9 3950X and the Ryzen 9 5950X in multi-thread performance. This is a great result, as of mid 2022.
