Ryzen 7 5800 vs Core i9-11900KF comparison

Our benchmark analysis concludes that the Ryzen 7 5800 performs better than the Core i9-11900KF. Despite this, the Core i9-11900KF has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count and the same number of threads. Our comparison shows that the Core i9-11900KF has a slightly higher clock speed compared to the Ryzen 7 5800. Also, the Core i9-11900KF has a slightly higher turbo speed. A Ryzen 7 5800 CPU outputs less heat than a Core i9-11900KF CPU because of its significantly 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 5800 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 5800 has more threads than cores. Each physical core is split into multiple threads.
