The Core i9-13900KS is based on theCore i9-13900K's best bits, having  24 cores, 32 threads, eight P-cores and 16 E-cores. The industry had expected to see the Core i9-13900KS getting a performance uplift from improved clock speeds. This is because the Core i9-13900K hits 5.8 GHz through Intel's Thermal Velocity Boost (TVB) technology, whereas the Core i9-13900KS will reach 6 GHz. The extra 200 MHz will lift the Core i9-13900KS slightly over the Core i9-13900K.

Hardware detective Benchleaks spotted three Geekbench 5 submissions for the Core i9-13900K.

Intel Core i9-13900KS Benchmarks
Processor Single-Core Score Multi-Core Score
Core i9-13900KS 2,319 26,774
Core i9-13900K 2,227 24,311
Ryzen 9 7950X 2,192 22,963
Core i9-12900KS 2,081 19,075
Core i9-12900K 1,988 17,324

The Core i9-13900K was up to 10.1 per cent faster than the Core i9-13900K. It was ahead of the Core i9-12900KS and Core i9-12900K by 40.4 per cent and 54.5 per cent respectively.

What is good news for Intel is that its new chip cleans AMD's clock in the flagship space. The Ryzen 9 7950X could not match the Core i9-13900KS, either, with the 6 GHz chip obtaining a 16.6 per cent higher multi-core score.

The Core i9-12900KS was the fastest gaming processor that money could buy, and the title was taken by the Ryzen 7 5800X3D. The Core i9-13900KS should restore Intel's crown, but with AMD is reportedly cooking up to three Ryzen 7000 3D V-Cache chips for 2023 it might not hold it for long.
