Core i5-6400 vs FX-8120 comparison

In our benchmarks, the FX-8120 beats the Core i5-6400 in overall performance. Despite this, the Core i5-6400 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the FX-8120 has more threads. These CPUs have different clock speeds. Indeed, the FX-8120 has a slightly higher clock speed compared to the Core i5-6400. A Core i5-6400 CPU outputs less heat than a FX-8120 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-8120 has significantly more L2 cache than the Core i5-6400. The FX-8120 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 i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
