Core i7-7700K vs Core i5-12400F specs and performance

Our benchmark analysis concludes that the Core i5-12400F performs better than the Core i7-7700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7700K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-12400F has significantly more cores than the Core i7-7700K. Indeed, the Core i5-12400F has 6 cores compared to 4 cores found in the Core i7-7700K. It also has more threads than the Core i7-7700K. Our comparison shows that the Core i7-7700K has a significantly higher clock speed compared to the Core i5-12400F. Also, the Core i7-7700K has a slightly higher turbo speed. The Core i5-12400F outputs less heat than Core i7-7700K 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. Indeed, the Core i7-7700K has more threads than cores. Each physical core is split into multiple threads.
