Core i5-8600 vs Core i5-9600K specs and performance

In our benchmarks, the Core i5-9600K beats the Core i5-8600 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8600 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core i5-9600K has a slightly higher clock speed than the Core i5-8600. Also, the Core i5-9600K has a slightly higher turbo speed. A Core i5-8600 CPU outputs less heat than a Core i5-9600K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches and 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 i5-8600 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
