Intel Core i9-11900F vs Intel Core i5-12400

Core i9-11900F vs Core i5-12400 benchmarks

Our benchmark analysis concludes that the Core i9-11900F performs better than the Core i5-12400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-12400 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-11900F has slightly more cores with 8 cores compared to the Core i5-12400 that has 6 cores. It also has more threads than the Core i5-12400. According to our data, the Core i9-11900F and Core i5-12400 have the same clock speed. Despite this, the Core i9-11900F 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.

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 i9-11900F has more threads than cores. Each physical core is split into multiple threads.
