Intel Core i7-11700K vs Intel Core i9-9900KF

Core i7-11700K vs Core i9-9900KF comparison

In our benchmarks, the Core i7-11700K 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.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Both the Core i7-11700K and Core i9-9900KF have the same clock speed. In addition, both chips have the same turbo speed. The Core i9-9900KF outputs less heat than Core i7-11700K thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i7-11700K has significantly more L2 cache than the Core i9-9900KF. However, both these chips have the same amount of 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 Core i7-11700K has more threads than cores. Each physical core is split into multiple threads.
