Ryzen 7 3800X vs Core i5-8600K specs and performance

Our benchmark analysis concludes that the Ryzen 7 3800X performs better than the Core i5-8600K. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8600K in all gaming tests too.

With info from our database, we find that the Ryzen 7 3800X has slightly more cores with 8 cores whereas the Core i5-8600K has 6 cores. It also has more threads than the Core i5-8600K. With our hardware info, we find that the Ryzen 7 3800X has a slightly higher clock speed than the Core i5-8600K. Also, the Ryzen 7 3800X has a slightly higher turbo speed. The Core i5-8600K outputs less heat than Ryzen 7 3800X thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Ryzen 7 3800X has significantly more L2 cache when compared to the Core i5-8600K. The Ryzen 7 3800X also has significantly 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 Ryzen 7 3800X has more threads than cores. Each physical core is split into multiple threads.
