Practically, we know details about all of the Intel Rocket Lake-S, 11th Generation desktop processors, but today we have one more piece of information to complete the details of Intel Core i9-11900K, the top-end model with a configuration of 8 cores and 16 threads under the Cypress Cove @ 14nm +++ architecture that will be able to reach a Turbo frequency for single core @5.30 GHz while all of them in operation will reach 4.80 GHz. Now this we know that it will have a power consumption of 250W (PL2).

This translates into having the same power consumption as the Intel Core i9-10900K, with the exception that this CPU offers 2 extra cores, 10 cores and 20 processing threads. At Base frequencies, both also have a consumption of 125W.

It should be remembered that the  Intel Rocket Lake-S features new Cypress Cove cores, an adaptation @ 14nm +++ of the Sunny Cove microarchitecture that brings Intel Ice Lake portable processors to life on 10nm manufacturing process, and not the improved 10nm (SuperFin) with Willow Cove microarchitecture that brings Tiger Lake CPUs to life. Due to the size, the company will be forced to limit its processors to a maximum of 8 cores and 16 threads.

According to the company, the main advantages are improvement in the IPC (which we only know is double-digit compared to an Intel Core i9-10900K), the improvement of the integrated graphics by implementing the Intel Xe-LP, PCI-Express 4.0 with up to 20 lines, controller for DDR4 @ 3200 MHz memory, and the addition of USB 3.2 Gen 2×2 @ 20 Gbps ports.

These CPUs will go on sale in March 2021 and Intel Core i7s are expected to cost less than $ 400 compared to Core i5s that cost less than $ 300, so Intel’s strategy will be to offer more cores than AMD at a lower price.
