Core i5-6600K vs Core i7-6700 comparison

According to the hardwareDB Benchmark tool, the Core i7-6700 is faster than the Core i5-6600K. Despite this, the Core i5-6600K has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores but the Core i7-6700 has more threads. Our comparison shows that the Core i5-6600K has a slightly higher clock speed compared to the Core i7-6700. Despite this, the Core i7-6700 has a slightly higher turbo speed. The Core i7-6700 outputs less heat than Core i5-6600K thanks to a slightly lower TDP. 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. The Core i7-6700 also has slightly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i5-6600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
