Intel Core i7-11700KF vs Intel Core i9-11900KF

Core i7-11700KF vs Core i9-11900KF comparison

Our benchmark analysis concludes that the Core i9-11900KF performs better than the Core i7-11700KF. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-11700KF in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. With our hardware info, we find that the Core i7-11700KF has a slightly higher clock speed than the Core i9-11900KF. Despite this, the Core i9-11900KF 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. When comparing cache sizes, these CPUs have an identical amount of L2 cache and 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 i7-11700KF has more threads than cores. Each physical core is split into multiple threads.
