Energy Efficiency

No surprise here; the power consumption figures echo those we arrived at while testing with integrated graphics. On light load, the 5700 is very similar to the 5600K and 5800K. On heavy load, the 5700 pulls ahead, especially on synthetic loads.

For some extra context, we've determined what we call the "average power consumption" which assumes the system is used half the time for light load activities (an average of idle and H.264 playback) and the remaining half for heavy load (an average of the power consumption used running our five benchmarks). We believe this is a very common usage scenario for an average PC — they are often left on for long periods of time, doing little to no work.

In this scenario, the A10-5700 leads the A10-5800K by 8W, edges out the A8-5600K by 2W, and comes close to matching the Sandy Bridge Core i5-2500K.

For users with heavy workloads, the total power consumed while running our benchmark suite is of pertinent interest. The total power takes into account the energy efficiency of each CPU while running our benchmark tests as well as how quickly they complete each task. This simulates the power draw of a machine that is purely for doing work and shuts down when its job is finished.

When it comes to getting things done, the A10-5700 had only a marginal power advantage over the A8-5600K and a fair way to go to compete with Intel's offerings.
