Throughout all of our benchmarking and testing, we also monitored how much power our test systems consumed using a power meter. Our goal was to give you all an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the processors alone.
Idle power consumption is surprisingly similar between the various platforms we tested, with only a 6 watt spread separating AMD's latest Trinity-based APUs and Intel's Ivy Bridge-based offerings. Under load conditions, however, the AMD platforms consumed significantly more power than Intel's and virtually the same as the previous-gen Llano-based A8-3870K.
Though actual power consumption is similar between the A8-3870K and newer A10-5800K and A8-5600K, efficiency is improved with Trinity / Virgo. Both the A10-5800K and A8-5600K offer better overall and graphics performance than the older A8-3870K, but we'll have to save all of those details for our follow-on article we're working on for next week.
