FX-8120 vs Xeon E5-2420 comparison

Our benchmark analysis concludes that the FX-8120 performs better than the Xeon E5-2420. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2420 in all gaming tests too.

With info from our database, we find that the Xeon E5-2420 has significantly more cores with 6 cores whereas the FX-8120 has 4 cores. It also has more threads than the FX-8120. Our comparison shows that the FX-8120 has a significantly higher clock speed compared to the Xeon E5-2420. The Xeon E5-2420 outputs less heat than FX-8120 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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. Indeed, the FX-8120 has more threads than cores. Each physical core is split into multiple threads.
