Intel Core i5-12400F vs Intel Core i9-12900KS

Core i5-12400F vs Core i9-12900KS comparison

Our benchmark analysis concludes that the Core i9-12900KS performs better than the Core i5-12400F. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-12400F in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-12900KS has significantly more cores with 16 cores compared to the Core i5-12400F that has 6 cores. It also has more threads than the Core i5-12400F. With our hardware info, we find that the Core i9-12900KS has a slightly higher clock speed than the Core i5-12400F. Also, the Core i9-12900KS has a slightly higher turbo speed. A Core i5-12400F CPU outputs less heat than a Core i9-12900KS CPU because of its 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 i5-12400F has more threads than cores. Each physical core is split into multiple threads.
