Six Socket FM2 Motherboards For AMD's Trinity APUs

Power, Heat, And Efficiency

ASRock's FM2A85X Extreme6 takes a fairly big lead when it comes to energy consumption under full load, but there’s a trick behind that reading: each board attempts to cram our CPU into a specific power envelope through dynamic underclocking. The other boards would eventually idle down by around 10 W, and give up around 400 MHz while doing that. ASRock’s FM2A85X Extreme6 idled down a little faster, and we weren’t able to get its “real” full-load reading.

MSI's FM2-A85XA-G65 runs the coolest during our extended full-load test, though each board throttles down AMD's APU during the run. Disabling power management features is one way to combat this behavior. However, in the real-world, you're going to want to run with them enabled to avoid wasting power. That's why we leave them enabled throughout the benchmarks.

Using an average of averages to compare performance to power consumption, we find ASRock’s 7% power savings worth an 8% efficiency increase. Noting that the board had already began to throttle back before we could get a load reading, we estimate that the FM2A85X Extreme6 would normally place around mid-pack. This is one of those rare situations where Chris’ extended power readings (total watts required to complete the entire benchmark series) would have been more-enlightening.

We don’t have to make an estimation to understand why MSI doesn't do well in terms of efficiency, since the power consumption chart shows high idle wattage.

    And I would penalize Asrock for the brown PCB. Its an otherwise nice looking board, but this is a trend I don't care for.

    Why, why do you keep posting Skyrim as being a DirectX11 title? It IS NOT. It's just DX9

    SakkuraSneaky, lol. Now he's going to be downvoted.Not sneaky, I just see a lot of sniping in here. I checked the article and didn't find it, and I really need to find it before I can gripe at the person who made the final revisions to this article. His comment could be completely false for all I know...

Even if you have a case with an acrylic window, do you stare into your PC all day and night? If so, that is trend I don't care for.

    There are much more important things to worry about, like quality, price, and features, to name a few...

    just one?

    :lol:
    who cares, good job to crash and the rest of the crew . . .
