Intel Core i9-11900K fails to beat the Ryzen 9 5950X in IPC

Based on the latest leaks on the performance of the Intel Core i9-11900K, it appears that the top-of-the-range Rocket Lake-S fails to outperform AMD's current top-of-the-line desktop range, the Ryzen 9 5950X.

Intel Core i9-11900K belongs to the Rocket Lake-S generation and it is a CPU with 8 cores and 16 threads that work with a base clock speed of 3.50 GHz and an increased clock speed of 5.30 GHz. Its TDP is 125 W.

The new Rocket Lake-S architecture promises to offer a huge improvement in IPC (number of instructions per clock) performance, but that leap wouldn't be enough to compete against the Ryzen 5000s, based on these leaked benchmarks.

Testing was done with the Cinebench R23, Cinebench R20, Cinebench R15, and CPU-Z tools. In all tests, the Ryzen 9 5950X is superior to the Intel Core i9-11900K, although there is a big improvement over the Comet Lake-S.

The tests were conducted by limiting the number of cores in both to 4 cores and 8 threads with the same 4 GHz clock speeds. The Ryzen 9 5950X manages to outperform the Intel Core i9-11900K by between 6% and 10%. Limiting the number of cores for these tests is necessary to have both on equal footing because the AMD option has 16 cores and 32 threads.

The 11th Gen Intel Core Rocket Lake-S processors are officially released on March 30.
