AMD Ryzen 7 5800X vs Intel Core i9-11900K

Ryzen 7 5800X vs Core i9-11900K benchmarks

In our benchmarks, the Core i9-11900K beats the Ryzen 7 5800X in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 7 5800X in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 7 5800X 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 5800X 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. The data shows that both these CPUs have same sized L2 caches. The Ryzen 7 5800X also has significantly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Ryzen 7 5800X has more threads than cores. Each physical core is split into multiple threads.
