Intel Core i7-8700K vs Intel Core i5-12400

Core i7-8700K vs Core i5-12400 specs and performance

According to the hardwareDB Benchmark tool, the Core i5-12400 is faster than the Core i7-8700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8700K in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Core i7-8700K has a significantly higher clock speed compared to the Core i5-12400. Also, the Core i7-8700K has a slightly higher turbo speed. The Core i5-12400 outputs less heat than Core i7-8700K 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 i7-8700K has more threads than cores. Each physical core is split into multiple threads.
