Intel Core i5-8600K vs AMD FX-8320

Core i5-8600K vs FX-8320 specs and performance

In our benchmarks, the Core i5-8600K beats the FX-8320 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the FX-8320 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-8600K has significantly more cores with 6 cores compared to the FX-8320 that has 4 cores. Despite this, the FX-8320 has more threads than the Core i5-8600K. These CPUs have different clock speeds. Indeed, the Core i5-8600K has a slightly higher clock speed compared to the FX-8320. A Core i5-8600K CPU outputs less heat than a FX-8320 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the FX-8320 has significantly more L2 cache when compared to the Core i5-8600K. Despite this, the Core i5-8600K has slightly more L3 cache compared to the FX-8320.

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.
