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

According to the hardwareDB Benchmark tool, the Core i7-11700K is faster than the Core i7-6700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6700K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-11700K has significantly more cores than the Core i7-6700K. Indeed, the Core i7-11700K has 8 cores compared to 4 cores found in the Core i7-6700K. It also has more threads than the Core i7-6700K. These CPUs have different clock speeds. Indeed, the Core i7-6700K has a slightly higher clock speed compared to the Core i7-11700K. Despite this, the Core i7-11700K has a slightly higher turbo speed. The Core i7-6700K outputs less heat than Core i7-11700K thanks to a slightly 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 i7-11700K has significantly more L2 cache than the Core i7-6700K. The Core i7-11700K 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 i7-11700K has more threads than cores. Each physical core is split into multiple threads.
