Intel Core i9-12900K benchmark leak puts the Alder Lake-S processor way beyond the capabilities of the AMD Ryzen 9 5950X while embarrassing the Core i9-11900K and Core i9-10900K

Based on leaked benchmark results, the Core i9-12900K will be more competition to AMD than the Core i9-11900K has been. Supposedly, the Core i9-12900K outscores the Ryzen 9 5950X by up to 25% and the Core i9-11900K by over 90%.

Intel's Alder Lake-S processors may not be here yet, but OneRaichu has provided an insight into how well the flagship model performs. For context, Intel is expected to release the Core i5-12600K, Core i7-12700K and Core i9-12900K, which will all feature performance Golden Cove cores and more power-efficient Gracemont cores. This combination will give the Core i9-12900K 16 cores and 24 threads, with the Core i5-12600K dropping to 10 cores.

Writing on Twitter, OneRaichu reports that the Core i9-12900K has scored 810 points in Cinebench R20's single-threaded benchmark and 11,600 points in the multi-threaded one. While these scores cannot be verified, OneRaichu has a solid reputation, to date. They also emphasise that this processor is a qualification sample (QS), so its performance may differ from retail units. Nonetheless, these scores put the Alder Lake-S well beyond its peers.

According to our database, a single-threaded score of 810 points puts the Core i9-12900K 25% ahead of the Core i9-11900K and 26% beyond the Ryzen 9 5950X. Additionally, the Core i9-12900K enjoys a 52% lead over the Core i9-10900K. The gap from the Core i9-10900K and Core i9-11900K to the Core i9-12900K in the multi-threaded benchmark is even larger at 82% and 93%, respectively.

The Core i9-12900K also outscores the Ryzen 9 5950X by 11%, which also has 16 cores. However, we should stress that the Core i9-12900K supposedly achieved these scores attached to an AIO. Similarly, OneRaichu states that the Core i9-12900K could consume over 200 W under full load; VideoCardz reports a PL2 value of 228 W, for reference.
