Intel Core i7-9700KF vs Intel Core i9-9900K

Core i7-9700KF vs Core i9-9900K benchmarks

In our benchmarks, the Core i9-9900K beats the Core i7-9700KF in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-9700KF in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i9-9900K has more threads. Both the Core i7-9700KF and Core i9-9900K have the same clock speed. Despite this, the Core i9-9900K has a slightly higher 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. The Core i9-9900K also has slightly more 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. For instance, the Core i7-9700KF has the same number of threads as cores. This means the the CPU does not support hyperthreading.
