Intel i9-11900KB

The Intel Core i9-11900KB is an Octa-Core-CPU that was used in the Intel Beast Canyon NUC. It is based on the Tiger-Lake-H45 series and was announced in the second quarter of 2021. The processor cores can clock from 3.3 to 5.3 GHz, all cores at once can reach up to 4.9 GHz. The CPU features 24 MB level 3 cache and DDR4-3200 memory. The integrated UHD graphics card is based on the Xe-architecture with 32 cores and clocks up to 1.45 GHz.

As with the slower Tiger Lake-H CPUs, the 11900KB has a partly integrated WiFi 6E and Thunderbolt 4 in the chip. Furthermore, the 11900KB supports 20 PCIe 4.0 lanes.

The TDP is rated at 65 Watt with 3.3. GHz base clock and can be configured to 55 Watt (cTDP-down).
