Power consumption was measured after 10 minutes of load under three scenarios: Furmark GPU stress test, Unigine Valley looping at the Extreme HD preset and desktop idle. The measurement was taking using an Energenie ENER007 power meter and measured for the whole system, excluding the monitor.
While Furmark and desktop idle provide stable and consistent power read-outs, Unigine Valley does not so the power reading is taken as the highest value in Scene 1 of 18.
Power consumption is immensely impressive and AMD still has some way to go to match Nvidia's power efficiency. Despite consistently beating the RX 480, the GTX 1060 consumes less power and even manages to be more efficient than the last-gen GTX 950 while offering bags more performance.
