Product Description

Intel Core i9-11900 is a premium desktop microprocessor in Intel's 11th-gen Core, Rocket Lake family. Compared to the i7-11700, this i9 CPU offers a slight bump in turbo frequency but is otherwise identical. Compared to the i9-11900K, its max turbo frequency is marginally lower and is rated at a lower TDP. Naturally, the K-series model is unlocked.
Compared to its predecessor, the Core i9-11900 comes with only 8 cores and 16 threads; this is the result of backporting Cypress Cove to the 14nm process. Intel claims that up to 22% IPC (instructions per clock) increase may be observed over the 10th-gen Comet Lake units under the best-case scenarios. Another area where Intel improved is the integrated graphics, now named Intel UHD 750, which observes higher base and boost frequencies than the previous-gen UHD 630.
The new Rocket Lake processors support DDR4-3200MHz memories, though the i9-11900 defaults to 2:1 ratio of DRAM to memory controller at this frequency. Intel also includes PCIe 4.0 support with up to 20 lanes.
Alongside the i9-11900, Intel also markets the Core i7-11900F. The "F" designation means the i9-11900F does not come with the integrated graphics. There is also a low-powered i9-11900T with 35W TDP rather than the 65W TDP of the base model; it also offers a TDP-down mode that is missing from the base i9-11900.
