Intel Core i5-9400F vs Intel Core i9-12900K

Core i5-9400F vs Core i9-12900K specs and performance

Our benchmark analysis concludes that the Core i9-12900K performs better than the Core i5-9400F. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400F in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i9-12900K has significantly more cores than the Core i5-9400F. Indeed, the Core i9-12900K has 16 cores compared to 6 cores found in the Core i5-9400F. It also has more threads than the Core i5-9400F. With our hardware info, we find that the Core i9-12900K has a slightly higher clock speed than the Core i5-9400F. Also, the Core i9-12900K has a slightly higher turbo speed. A Core i5-9400F CPU outputs less heat than a Core i9-12900K CPU because of its significantly lower TDP. 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.
