Core i9-12900K is a 64-bit hexadeca-core high-end performance x86 desktop microprocessor introduced by Intel in late 2021. This processor, which is based on the Alder Lake microarchitecture, is manufactured on Intel's Intel 7 process. The i9-12900K is a heterogeneous multicore SoC integrating eight big Golden Cove cores along with eight small Gracemont cores. The big cores operate at 3.2 GHz with a Turbo Boost frequency of up to 5.1 GHz and a Turbo Boost Max frequency of up to 5.2 GHz. The small cores operate at 2.4 GHz with a Turbo Boost frequency of up to 3.9 GHz. This processor has a base power of 125 W and a maximum turbo power of 241 W. This chip supports up to 128 GiB of dual-channel DDR5-4800 memory and incorporates Intel's UHD Graphics 770 IGP operating at 300 MHz with a burst frequency of 1.55 GHz.
The i9-12900KF is an identical version of this chip without integrated graphics.
