AMD FX-8120 Black Edition CPU Review (with Asus M5A99X EVO)

In this review we are going to benchmark the AMD FX-8120 Black Edition at reference clock speeds and when overclocked to 4.2 GHz. We will be comparing it to a similarly specified i5-2500K based system which is detailed below. A 2500 is priced around £170 inc vat in the UK today – this is one of Intel’s most popular mid range processors in the enthusiast sector. The FX-8120 is priced around £135 inc vat in the UK today. AMD motherboards are still generally quite expensive however, so the overall cost of ownership can tend to balance out.

All Intel Core i5 processors overclock to 4.2ghz easily enough, even the Core i5 2300, so it is almost irrelevant which Intel Core i5 we use for comparison in an overclocked state today.

We used a Noctua NH-D14 to cool the AMD FX-8120 Black Edition and a Phanteks PH-TC14PE to cool the i5-2500K.
