Final Thoughts and Conclusion

VGA Power Consumption

Life is not as affordable as it used to be, and items such as gasoline, natural gas, and electricity all top the list of resources which have exploded in price over the past few years. Add to this the limit of non-renewable resources compared to current demands, and you can see that the prices are only going to get worse. Planet Earth needs our help, and needs it badly. With forests becoming barren of vegetation and snow capped poles quickly turning brown, the technology industry has a new attitude towards turning "green". I'll spare you the powerful marketing hype that gets sent from various manufacturers every day, and get right to the point: your computer hasn't been doing much to help save energy... at least up until now.

For power consumption tests, Benchmark Reviews utilizes an 80-Plus Gold rated Corsair HX750w (model: CMPSU-750HX) This power supply unit has been tested to provide over 90% typical efficiency by Ecos Plug Load Solutions. To measure isolated video card power consumption, I used the energenie ENER007 power meter made by Sandal Plc (UK).

A baseline test is taken without a video card installed inside our test computer system, which is allowed to boot into Windows-7 and rest idle at the login screen before power consumption is recorded. Once the baseline reading has been taken, the graphics card is installed and the system is again booted into Windows and left idle at the login screen. Our final loaded power consumption reading is taken with the video card running a stress test using FurMark. Below is a chart with the isolated video card power consumption (not system total) displayed in Watts for each specified test product:

* Results are accurate to within +/- 5W.

At Idle the MSI R6950 Twin Frozr III PE/OC consumes 54 (166-119) watts at idle and 227 (346-119) watts when running full load using the test method outlined above. Contrary to what we see in the GPU-Z screenshot below the MSI R6950 Twin Frozr III Power Edition OC uses 0.899v when idle, when under load it uses 1.149v.

I would be interested to know what the quietest video card is, on a model to model basis. For example, what is the quietest 560 running full out? The quietest 6870? Etc.

A lot of us are making quiet machines. The noisiest parts are our gpu's. And I'm not ready to go fanless yet.

May be this is what you're looking for-XFX HD 6870 Black (##anandtech.com/show/4137/amds-gtx-560-ti-counteroffensive-radeon-hd-6950-1gb-xfxs-radeon-hd-6870-black-edition/6). This one seems to have excellent acoustic properties.

Ehume you may want to look at the passively cooled Powercolor 6850.

AMD should take some notes from Nvidia's page. HD6950 has so much potential (leaving alone the unlocking/flashing to 6970), yet board partners can't tweak it to their heart's content without cannibalizing the sell of HD6970 - a real shame! Look at those custom clocked 560-ti cards, it's hard to find a reference one now days. Similarly every non-reference 6950 2GB should come out with at least 900Mhz at the gpu core.

*You guys @BMR seem to be on a roll with these hot video card reviews, keep it that way:)

I'm waiting for Aussie prices to drop, but it might help if I knew whether AMD and Nvidia, both, are equal in heat, power use and decibels, to each other for performance output.
We can Google and find info, but usually the tests are from different testers on different machines, rendering the tests irrelevant.
