Benchmarks for the upcoming Intel Rocket Lake-S flagship CPU, Core i9-11900K have leaked out online. The benchmarks show a huge gain in single-core performance for the upcoming flagship. The CPU was tested by a media outlet at Bilibili and was compared against AMD’s Ryzen 7 5800X and a Ryzen 7 5700G, the latter also being an unreleased CPU.
The Core i9-11900K is the flagship processor of the upcoming Intel 11th Gen Rocket Lake-S CPU series. It is based on the Cypress cove architecture which is the biggest CPU architectural upgrade in over 5 years. Ever since the 6th Generation Skylake CPUs, all Intel CPUs up till the 10th Generation Comet Lake CPUs used the same identical chip architecture based on the 14nm process node, with small refinements along the way.
The Intel Core i9-11900K will have 8 cores and 16 threads, 16 MB of L3 cache (2 MB per core), and 4 MB of L2 cache (512 KB per core). In terms of clocks, the CPU has a base frequency of 3.5 GHz but as for boost, the CPU will feature a maximum boost clock of 5.3 GHz (1-core) while the all-core boost frequency will be maintained at 4.8 GHz, powered by Intel Thermal Velocity Boost.
In the leaked benchmark, the i9-11900K CPU was running on a Z590 motherboard using a newer BIOS than what is currently being shipped in retail. In the CPU-Z benchmark, the i9-11900K is faster than both Ryzen 5800X and 5700G in both single and multi-core benchmarks.
However, in gaming, the performance is not up to the mark for Intel’s upcoming flagship CPU. Despite a massive clock speed overclock of 5.2 GHz, the Intel Core i9-11900K barely matches the Ryzen 7 5800X & even loses to the AMD competitor in a few gaming tests.

Keep in mind that the Rocket lake flagship is an engineering sample so we may see better performance once the processor is released officially.
