Core i3-10300 vs Core i5-8600K comparison

Our benchmark analysis concludes that the Core i5-8600K performs better than the Core i3-10300. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-10300 in all gaming tests too.

With info from our database, we find that the Core i5-8600K has significantly more cores with 6 cores whereas the Core i3-10300 has 4 cores. Despite this, the Core i3-10300 has more threads than the Core i5-8600K. Our comparison shows that the Core i3-10300 has a slightly higher clock speed compared to the Core i5-8600K. Also, the Core i3-10300 has a slightly higher turbo speed. A Core i3-10300 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 i3-10300. The Core i5-8600K also has slightly more L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i3-10300 has more threads than cores. Each physical core is split into multiple threads.
