Intel Core i9-11900K produces an ominous Geekbench single-core result that takes the i9-10900K by +32% and leaves the AMD Ryzen 7 5800X and Ryzen 9 5950X out of sight

The 8-core, 16-thread Intel Core i9-11900K has been spotted on Geekbench, courtesy of Tum Apisak, and it has not disappointed in terms of single-core performance. The Rocket Lake-S sample produced a score of 1,892 points, which would be enough to put it far and away ahead of anything else on Geekbench’s charts if it stood as an average result. The clock rates were recorded at 3.50 GHz to 5.28 GHz and the i9-11900K was assisted by a Z490 Aorus Master motherboard.

This tremendous single-core result is no less than +32.49% greater than the median results we have achieved with the Comet Lake i9-10900K. Even if we compare it with our maximum result for the predecessor, which was 1,449 points, the Intel Core i9-11900K still has a +30.57% gain. As for the competition, Geekbench’s chart shows similar results to what we achieved with the 8-core Ryzen 7 5800X and 16-core Ryzen 9 5950X. If we use the slightly higher scores from the benchmark site, the i9-11900K still commands a lead of +13.36% (Ryzen 7 5800X) and +12.49% (Ryzen 9 5950X), respectively. But these are average scores for the AMD parts, and a later post from Apisak (see below) revealed that the Intel chip can still nose ahead of higher-performing examples of the competition here, albeit by much lower margins.

It’s an ominous single-core showing by the Intel Core i9-11900K that could easily sweep away the less positive aspects of this Rocket Lake-S monster. The multi-core score here of 10,934 points is nothing remarkable (Ryzen 7 5800X: 11,354 points Notebookcheck; 10,427 points Geekbench average), and there is the power advantage that Team Blue utilizes that needs to be kept in mind. The i9-11900K has TDPs of 125 W (PL1) and 250 W (PL2) while the Ryzen 5000 parts rely on 105 W. But this is the kind of result that will make desktop PC builders focused on single-core performance sit up and take notice.
