Power Consumption

For testing power consumption, we took our test system and plugged it into a Kill-A-Watt power meter. For idle numbers, we allowed the system to idle on the desktop for 15 minutes and took the reading. For load numbers we measured the peak wattage used by the system while running the OpenGL benchmark FurMark 1.9.2 at 640x480 resolution. We also ran the game HAWX 2 and looped the benchmark three times and recorded the highest Wattage seen on the meter. 

Total System Power Consumption Results

Power Consumption Results: The AMD Radeon HD 7700 series does exceptionally well when it comes to power efficiency. AMD put a ton of engineering work into PowerTune and ZeroCore power technologies on the new core architecture and the fruits of their labor are really starting to show it. The AMD Radeon HD 7000 series has impressive power numbers and you can see what AMD claims below.
