Intel Core i9-11900K 11th Gen ‘Rocket Lake’

All 11th Gen ‘Rocket Lake’ CPUs will be compatible with previous-gen 400-series chipsets except the low-end B460 and H410, and all 10th Gen ‘Comet Lake’ CPUs will continue to work with new 500-series motherboards. You’ll need a 500-series motherboard to harness PCIe 4.0, integrated USB 3.2 Gen 2×2, and faster DMI interconnect with the latest CPUs. Interestingly, Intel now allows memory overclocking on even mid-range 500-series motherboards.
