Core i9-11900K vs Core i9-11900KF benchmarks

Our benchmark analysis concludes that the Core i9-11900KF performs better than the Core i9-11900K. Despite this, the Core i9-11900K 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. In terms of clock speed, the Core i9-11900K and Core i9-11900KF are identical in this regard. In addition, both chips have the same turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache and 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 Core i9-11900K has more threads than cores. Each physical core is split into multiple threads.
