Intel Core i9-12900KS 16-core desktop processor

The Intel Core i9-12900KS is a 16-core desktop processor with 8 performance cores and 8 efficient cores delivering 24 threads. It operates at a 3.4 GHz P-core base frequency and reaches a 5.5 GHz maximum turbo frequency. The chip includes Intel UHD Graphics 770 and supports both DDR4 3200 and DDR5 4800 memory on the LGA 1700 platform.

Upgrade from 12th Gen Core i7

Moving from a Core i7 or i5 in the same 12th Gen family adds eight extra cores and raises the peak turbo to 5.5 GHz via Thermal Velocity Boost. The jump is worthwhile when workloads scale across 24 threads such as video encoding, 3D rendering or heavy multitasking. The 241 W maximum turbo power demands robust cooling and a motherboard rated for that level.

Check LGA 1700 socket DDR4

Verify the motherboard uses the LGA 1700 socket and supports the chosen DDR4 3200 or DDR5 4800 memory type. Confirm the CPU cooler and power delivery can handle 241 W maximum turbo power because no cooling device is included. Ensure the BIOS version supports this processor before installation.

Questions about this item

What cooler clearance and TDP rating do I need for the 150 W base / 241 W max turbo processor?

Plan for a cooler rated at least 241 W TDP that fits the LGA 1700 socket; the box contains no cooling device so you must supply one.

Which way does the LGA 1700 chip go in, and what step do builders often miss?

Align the notches on the substrate with the socket keys, lower the CPU gently, then lock the independent loading mechanism — forgetting to seat the ILM fully is the common error.

When should I replace the thermal interface material on this 16-core 24-thread CPU?

Reapply paste whenever you reseat the cooler or after a few years of 241 W turbo loads; the integrated UHD Graphics 770 die shares the same heatspreader.
