Core i5-6600K vs Core i5-10300H comparison

In our benchmarks, the Core i5-10300H beats the Core i5-6600K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6600K in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i5-10300H has more threads. These CPUs have different clock speeds. Indeed, the Core i5-6600K has a slightly higher clock speed compared to the Core i5-10300H. Despite this, the Core i5-10300H has a slightly higher turbo speed. The Core i5-10300H outputs less heat than Core i5-6600K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache. The Core i5-10300H also has slightly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-6600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
