When comparing core counts for these CPUs, we notice that the Core i5-13400 has slightly more cores with 10 cores compared to the Core i9-11900K that has 8 cores. But they both have the same number of threads. With our hardware info, we find that the Core i9-11900K has a slightly higher clock speed than the Core i5-13400. Also, the Core i9-11900K has a slightly higher turbo speed. The info from our database shows that the Core i5-13400 has more L2 cache than the Core i9-11900K. The Core i5-13400 also has slightly more L3 cache.

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