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

We measured the power consumption of our entire test system at the wall while loading the CPU using Prime95. We recorded results with the system at reference clock speeds and when overclocked to 4.2 GHz.

The Intel i5-2500K draws much less power than the FX-8120 at stock settings and when overclocked.  Even when overclocked much higher than the AMD FX-8150 (4.7ghz v 4.2ghz), the Intel 2500K consumers less power under load.
