Core i5-8600K vs Core i7-5820K benchmarks

Our benchmark analysis concludes that the Core i5-8600K performs better than the Core i7-5820K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-5820K in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i7-5820K has more threads. With our hardware info, we find that the Core i5-8600K has a slightly higher clock speed than the Core i7-5820K. Also, the Core i5-8600K has a slightly higher turbo speed. A Core i5-8600K CPU outputs less heat than a Core i7-5820K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i5-8600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
