These CPUs have different clock speeds. Indeed, the Core i5-8400 has a slightly higher clock speed compared to the Core i5-13420H. Despite this, the Core i5-13420H has a slightly higher turbo speed. The cache sizes of these CPUs are different. Indeed, the Core i5-13420H has significantly more L2 cache than the Core i5-8400. The Core i5-13420H 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. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
