Ryzen 7 3800XT vs Core i9-11900K specs and performance

In our benchmarks, the Core i9-11900K beats the Ryzen 7 3800XT in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 7 3800XT in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 7 3800XT has a slightly higher clock speed compared to the Core i9-11900K. Despite this, the Core i9-11900K has a slightly higher turbo speed. A Ryzen 7 3800XT CPU outputs less heat than a Core i9-11900K CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. When comparing cache sizes, these CPUs have an identical amount of L2 cache. The Ryzen 7 3800XT also has significantly more L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Ryzen 7 3800XT has more threads than cores. Each physical core is split into multiple threads.
