Intel Core i5-9400F vs Intel Core i5-12400F

Core i5-9400F vs Core i5-12400F benchmarks

In our benchmarks, the Core i5-12400F beats the Core i5-9400F in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400F in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i5-12400F has more threads. Our comparison shows that the Core i5-9400F has a slightly higher clock speed compared to the Core i5-12400F. Despite this, the Core i5-12400F has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-9400F has the same number of threads as cores. This means the the CPU does not support hyperthreading.
