Intel Core i5-8600K vs Intel Core i5-11400F

Core i5-8600K vs Core i5-11400F comparison

Our benchmark analysis concludes that the Core i5-11400F performs better than the Core i5-8600K. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8600K in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i5-11400F has more threads. These CPUs have different clock speeds. Indeed, the Core i5-8600K has a slightly higher clock speed compared to the Core i5-11400F. Despite this, the Core i5-11400F has a slightly higher turbo speed. The Core i5-11400F outputs less heat than Core i5-8600K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i5-8600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
