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

According to the hardwareDB Benchmark tool, the Core i9-11900K is faster than the Core i7-11700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-11700K in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Core i7-11700K has a slightly higher clock speed compared to the Core i9-11900K. Despite this, the Core i9-11900K 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 i7-11700K has more threads than cores. Each physical core is split into multiple threads.
