Core i9-9900K vs Core i9-9900KF benchmarks

In our benchmarks, the Core i9-9900K beats the Core i9-9900KF in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900KF in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Both the Core i9-9900K and Core i9-9900KF have the same clock speed. 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. When comparing cache sizes, these CPUs have an identical amount of L2 cache and L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i9-9900K has more threads than cores. Each physical core is split into multiple threads.
