"Rocket Lake-S" is the name of the 11th generation of Intel Core processors. In addition to increased clock speeds compared to "Comet Lake-S" of the 10th generation, "Rocket Lake-S" supports higher memory clock rates and offers support for PCI Express 4.0 as well as an increased number of a total of 20 PCIe lanes compared to the previous generation.

The Intel Core i9-11900K 8-core processor with SMT and free multiplier

Thanks to the once again optimised 14nm manufacturing process, the Core i9-11900K offers a base clock speed of 3.5 GHz. With Intel Thermal Velocity Boost, the processor achieves a single-core max boost of 5.3 GHz, while all 8 cores (and 16 threads) can also be automatically overclocked up to 5.3 GHz boost clock. Depending on the type of application and cooling, the Core i9-11900K always achieves optimal performance thanks to the automatic boost clock. In addition, the Core i9-11900K has a free multiplier that enables manual overclocking in combination with an appropriate mainboard.

With the Intel Socket LGA 1200, the 11th generation of Intel Core processors has a socket for mounting on the mainboard. This means that the processor is only compatible with Intel mainboards with socket LGA 1200 and a chipset from Intel's 500 series. The number of pins remains the same at 1200, but mainboards with Intel Z590 support PCIe 4.0 for a graphics card as well as an SSD. The dimensions of the socket and the ILM (Independent Loading Mechanism) are still identical with the socket 1151/1155, which means that corresponding CPU coolers can continue to be used without the need for a conversion kit.

The Intel HD Graphics UHD 750 is used as the integrated graphics unit. With its 32 execution units, it offers more than enough graphics power for Intel Quick Sync video, GPU computing and of course the odd game in between. Furthermore, the graphics unit supports DirectX 12.1, OpenGL 4.5 and OpenCL 3.0 as well as the playback of 4K, UHD resolutions at 60 Hz via DisplayPort - provided an appropriate mainboard is available.

Note: This is a boxed version of the processor without CPU cooler!
