Intel Core i7-6700K vs Intel Core i7-11700F

Core i7-6700K vs Core i7-11700F comparison

In our benchmarks, the Core i7-11700F beats the Core i7-6700K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6700K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-11700F has significantly more cores with 8 cores compared to the Core i7-6700K that has 4 cores. It also has more threads than the Core i7-6700K. These CPUs have different clock speeds. Indeed, the Core i7-6700K has a significantly higher clock speed compared to the Core i7-11700F. Despite this, the Core i7-11700F has a slightly higher turbo speed. The Core i7-11700F outputs less heat than Core i7-6700K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i7-11700F has significantly more L2 cache than the Core i7-6700K. The Core i7-11700F also has significantly 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 i7-6700K has more threads than cores. Each physical core is split into multiple threads.
