FX-8120 vs Xeon E5-620 benchmarks

Our benchmark analysis concludes that the FX-8120 performs better than the Xeon E5-620. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-620 in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the FX-8120 has a slightly higher clock speed compared to the Xeon E5-620. Also, the FX-8120 has a significantly higher turbo speed. The Xeon E5-620 outputs less heat than FX-8120 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the FX-8120 has more L2 cache than the Xeon E5-620. The FX-8120 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 FX-8120 has more threads than cores. Each physical core is split into multiple threads.
