AMD Radeon HD 6790 1GB Video Card ReviewMon, Apr 04, 2011 - 11:00 PM
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 1.8.2 at 1280×1024 resolution.
Power Consumption Results: The AMD Radeon HD 6790 did so-so in the power consumption test as it drew 109W at idle and 249W at load. We call this so-so as it used more power than the AMD Radeon HD 6850 reference design and was slower than this card in all the benchmarks. We don’t like the fact that this card is slower than the AMD Radeon HD 6850, but still manages to use more power.
