What the Core i9-13900KS delivers

This refurbished 24-core desktop processor combines eight performance cores and sixteen efficient cores for 32 threads. Base clocks sit at 3.2 GHz on performance cores and 2.4 GHz on efficient cores, while maximum turbo reaches 5.4 GHz and 4.3 GHz respectively. Integrated Intel UHD Graphics 770 handles display output without a discrete card.

Upgrading from earlier LGA 1700 chips

Moving from a 12th or 13th generation Core i5 or i7 adds significant multi-thread throughput for rendering, compilation and heavy multitasking. The jump is worth it when workloads regularly saturate 16 threads or more and the platform already supports DDR5 5600 or DDR4 3200 memory. Unlocked multipliers allow manual tuning within thermal limits.

Platform checks before ordering

Verify the motherboard runs a BIOS version that supports 13th generation Raptor Lake CPUs and can deliver the 150 W base power envelope. Confirm the cooler is rated for that heat output and clears the LGA 1700 socket. Ensure the memory kit matches DDR4 3200 or DDR5 5600 specifications and does not exceed the 128 GB maximum capacity.

Questions about this item

Which socket and cooler clearance does the LGA 1700 Core i9-13900KS require?

It fits LGA 1700 motherboards; the processor ships without a cooler so you must supply a compatible air or liquid unit rated for at least 150 W thermal design power.

What BIOS step is often missed when installing this 24-core Raptor Lake CPU?

Update the motherboard BIOS to a version that supports 13th Gen Intel Core before mounting the processor, otherwise the system will not post.

When will the thermal paste on the Core i9-13900KS need replacement?

Reapply quality paste every two to three years or whenever the cooler is removed, because the integrated heatspreader transfers up to 150 W under load.
