Intel Core i3-9300 vs Intel Core i5-8600K

Core i3-9300 vs Core i5-8600K benchmarks

In our benchmarks, the Core i5-8600K beats the Core i3-9300 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-9300 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-8600K has significantly more cores than the Core i3-9300. Indeed, the Core i5-8600K has 6 cores compared to 4 cores found in the Core i3-9300. It also has more threads than the Core i3-9300. Our comparison shows that the Core i3-9300 has a slightly higher clock speed compared to the Core i5-8600K. Furthermore, both these CPUs have identical turbo speeds. A Core i3-9300 CPU outputs less heat than a Core i5-8600K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i5-8600K has significantly more L2 cache when compared to the Core i3-9300. The Core i5-8600K 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 i3-9300 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
