A comparison of Intel’s Core i9-10900K and the newly announced Rocket Lake-S flagship, the Core i9-11900K has surfaced on the Chinese BB forums. Both the chips were fixed at a boost clock of 5.2GHz and tested across half a dozen games.
Keep in mind that the retail version of the 11900K will run at a slightly higher frequency than the 10900K, but considering how few chips manage to hit the TVB (Thermal Velocity Boost) clock, I’d say that this is a fair comparison. In the CPU-Z benchmark, as expected, the Rocket Lake-S part has a huge lead in the single-threaded benchmark but falls behind in the multi-core test on account of the additional two cores on the 10900K.
Moving on to actual gaming benchmarks, you can see that the Core i9-11900K is actually slower than the Core i9-10900K in pretty much every game tested.
Although the deltas are often quite small (2-4 FPS), the 10900K consistently beats its successor across all six titles. This is likely on account of its higher core count. Most DX12 games, especially shooters tend to use as many as 12 cores which is what’s reflected in these benchmarks.
According to Intel’s own benchmarks, the Core i9-11900K is just 4% faster than the AMD Ryzen 9 5900X on average, and that’s in seven of the cherry-picked games the company decided to use. It’d be fair to assume that the actual performance delta in gaming workloads between the two processors will be negligible, or imperceivable at best.
The Cinebench scores reflect the same thing we saw in the CPU-Z benchmark. The 11900K has a pretty notable advantage in terms of single-threaded performance, but the 10900K still edges out in the multi-core benchmark.
It’ll be interesting to see how the Core i9-10900K and the 11900K perform out of the box and if the deltas between the two favor the former or the latter. It’s certainly going to be a unique situation if the 10900K manages to be faster or even on par with the 11900K.
