It also has more threads than the Core i5-11400. In terms of clock speed, the Core i5-11400 and Core i7-11700KF are identical in this regard. Despite this, the Core i7-11700KF has a slightly higher turbo speed. A Core i5-11400 CPU outputs less heat than a Core i7-11700KF CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Core i7-11700KF has more L2 cache than the Core i5-11400. The Core i7-11700KF 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 i5-11400 has more threads than cores. Each physical core is split into multiple threads.
