Intel Core i5-6600K vs Intel Core i7-8086K

Core i5-6600K vs Core i7-8086K specs and performance

Our benchmark analysis concludes that the Core i7-8086K performs better than the Core i5-6600K. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6600K in all gaming tests too.

With info from our database, we find that the Core i7-8086K has significantly more cores with 6 cores whereas the Core i5-6600K has 4 cores. It also has more threads than the Core i5-6600K. These CPUs have different clock speeds. Indeed, the Core i7-8086K has a slightly higher clock speed compared to the Core i5-6600K. Also, the Core i7-8086K has a slightly higher turbo speed. A Core i5-6600K CPU outputs less heat than a Core i7-8086K CPU because of its 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 i7-8086K has significantly more L2 cache than the Core i5-6600K. The Core i7-8086K 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. For instance, the Core i5-6600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
