Intel Core i7-7700K vs Intel Core i7-8086K

Core i7-7700K vs Core i7-8086K comparison

According to the hardwareDB Benchmark tool, the Core i7-8086K is faster than the Core i7-7700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7700K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-8086K has significantly more cores than the Core i7-7700K. Indeed, the Core i7-8086K has 6 cores compared to 4 cores found in the Core i7-7700K. It also has more threads than the Core i7-7700K. With our hardware info, we find that the Core i7-7700K has a slightly higher clock speed than the Core i7-8086K. Despite this, the Core i7-8086K 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. In terms of cache, the Core i7-8086K has significantly more L2 cache when compared to the Core i7-7700K. 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. Indeed, the Core i7-7700K has more threads than cores. Each physical core is split into multiple threads.
