Is the Intel Core i9-11900K right for you?
If you have a Z590 or B560 board and want the best chip available for it, the i9-11900K with its iGPU and PCIe 4.0 support is the platform's i9 peak at a low used price.
The i9-12900K on LGA1700 and used Zen 3 chips both deliver better performance. If either is available at a similar price, buy those instead.
Before you buy
Eight cores. Despite being the i9-11900K, it has fewer cores than the i9-10900K (10 cores) it nominally succeeded. Intel reduced cores in Rocket Lake to achieve higher clock speeds.
Rocket Lake uses a backported architecture that runs hot and draws more power than expected for its performance. Zen 3 from AMD beat it in gaming IPC, and Intel's own 12th gen Alder Lake dramatically outperformed it the following year.
LGA1200 with Intel 500-series boards (Z590, B560). It also works with 400-series boards (Z490) with a BIOS update, but Z590 is native.
Depends on the workload. The 11900K has higher single-core boost, PCIe 4.0, and better iGPU. The 10900K has more cores (10 vs 8) and is often cheaper. At similar prices, compare the specific workloads you need.
