Intel Core i7-9700K vs Intel Core i5-9400F

Core i7-9700K vs Core i5-9400F specs and performance

According to the hardwareDB Benchmark tool, the Core i7-9700K is faster than the Core i5-9400F. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400F in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-9700K has slightly more cores than the Core i5-9400F. Indeed, the Core i7-9700K has 8 cores compared to 6 cores found in the Core i5-9400F. It also has more threads than the Core i5-9400F. Our comparison shows that the Core i7-9700K has a slightly higher clock speed compared to the Core i5-9400F. Also, the Core i7-9700K has a slightly higher turbo speed. The Core i5-9400F outputs less heat than Core i7-9700K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i7-9700K has slightly more L2 cache when compared to the Core i5-9400F. The Core i7-9700K also has slightly more 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. For instance, the Core i7-9700K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
