Core i5-8400 vs Core i5-9600KF comparison

According to the hardwareDB Benchmark tool, the Core i5-9600KF is faster than the Core i5-8400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400 in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. With our hardware info, we find that the Core i5-9600KF has a slightly higher clock speed than the Core i5-8400. Also, the Core i5-9600KF has a slightly higher turbo speed. A Core i5-8400 CPU outputs less heat than a Core i5-9600KF CPU because of its significantly lower TDP. 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.

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 i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
