Core i5-9600K vs Core i5-12400F benchmarks

According to the hardwareDB Benchmark tool, the Core i5-12400F is faster than the Core i5-9600K. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9600K in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i5-12400F has more threads. With our hardware info, we find that the Core i5-9600K has a significantly higher clock speed than the Core i5-12400F. Also, the Core i5-9600K has a slightly higher turbo speed. The Core i5-12400F outputs less heat than Core i5-9600K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i5-9600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
