Core i5-7600K vs Core i7-8650U specs and performance

According to the hardwareDB Benchmark tool, the Core i5-7600K is faster than the Core i7-8650U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8650U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i7-8650U has more threads. These CPUs have different clock speeds. Indeed, the Core i5-7600K has a significantly higher clock speed compared to the Core i7-8650U. Furthermore, both these CPUs have identical turbo speeds. The Core i7-8650U outputs less heat than Core i5-7600K 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 i7-8650U 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 i5-7600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
