Core i9-12900KF 16-core desktop processor

The Intel Core i9-12900KF is a 16-core desktop processor built on the Intel 7 process. It combines eight performance cores and eight efficient cores for 24 threads total. Base clocks sit at 3.2 GHz on P-cores and 2.4 GHz on E-cores with turbo up to 5.2 GHz. The chip requires discrete graphics.

Suits threaded workloads.

This processor fits builders who need high thread counts for rendering, compilation or heavy multitasking. It supports DDR4 3200 and DDR5 4800 memory in dual-channel mode up to 128 GB. Buyers who want integrated graphics should choose a different model because this KF variant has none.

LGA 1700 socket with 241 W maximum turbo power

The CPU mounts in an LGA 1700 socket and has a processor base power of 125 W with a maximum turbo power of 241 W. A cooling solution is not included in the box. Ensure your motherboard and cooler can handle this power envelope before purchase.

Questions about this item

Will the LGA 1700 cooler need replacing if I push the 241 W turbo power?

The processor ships without a cooler, so a LGA 1700 solution rated for at least 241 W is required from day one.

What power ceiling hits first during an all-core workload?

The 241 W Maximum Turbo Power limit is reached before the 5.2 GHz single-core boost can be sustained across all 16 cores.

How hot and loud does the 125 W base power run under 24/7 load?

At the 125 W Processor Base Power the chip stays within its thermal design; actual temperature and fan noise depend entirely on the cooler you install.
