The Intel Core i9-12900KS is a desktop processor released in 2022, featuring 16 cores (8 P-cores and 8 E-cores) and 24 threads with a boost clock of up to 5.5 GHz.
The Intel Core i9-12900KS is a high-end desktop processor based on the Alder Lake microarchitecture, released in April 2022. It features a hybrid architecture with 8 Performance-cores (P-cores) and 8 Efficient-cores (E-cores), totaling 16 cores and 24 threads. The base clock is 3.4 GHz, with a maximum turbo boost of 5.5 GHz. It includes 14 MB of L2 cache and 30 MB of L3 cache, and is manufactured on a 7 nm process. The processor has a TDP of 150 W and a maximum turbo power of 241 W. It supports up to DDR5-4800 or DDR4-3200 memory across two channels, with ECC memory support. The integrated graphics is Intel UHD Graphics 770. It provides 20 PCIe lanes (PCIe 5.0 and 4.0) and uses the FCLGA1700 socket. The multiplier is unlocked for overclocking. Compatible chipsets include Intel 600-series (e.g., Z690, H670, B660, H610). The launch MSRP was $739 USD.
