AMD FX: Energy Efficiency Compared To Eight Other CPUs

Features
By , published

We've already seen AMD's Bulldozer architecture come up short in the performance benchmarks. However, the company also claims it made important improvements to power consumption. Can FX-8150 at least score some points in the energy efficiency department?

Single-Threaded Efficiency

AMD’s FX-8150 earns bad marks in applications that are not thread-optimized. Due to an ugly step backward in performance per clock cycle, the Bulldozer-based processor comes in last place.

Average power consumption is nothing to write home about, either.

Finally, we measure total power consumed during the test run of single-threaded applications. AMD uses about 40% more power, measured in watt-hours, than a comparable Intel system with a discrete graphics card.
