Intel Core i5-8400 vs AMD FX-8320

Core i5-8400 vs FX-8320 comparison

Our benchmark analysis concludes that the Core i5-8400 performs better than the FX-8320. Furthermore, our gaming benchmark shows that it also outperforms the FX-8320 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-8400 has significantly more cores than the FX-8320. Indeed, the Core i5-8400 has 6 cores compared to 4 cores found in the FX-8320. Despite this, the FX-8320 has more threads than the Core i5-8400. These CPUs have different clock speeds. Indeed, the FX-8320 has a slightly higher clock speed compared to the Core i5-8400. A Core i5-8400 CPU outputs less heat than a FX-8320 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the FX-8320 has significantly more L2 cache than the Core i5-8400. Despite this, the Core i5-8400 has slightly more L3 cache compared to the FX-8320.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
