PowerColor Go! Green HD5670 Video Card

For the environmentally, economically and otherwise interested parties, PowerColor has introduced a new line of graphics cards under the "Go! Green" banner. These cards aim to reduce power consumption by half while still competing with and beating the competition. Benchmark Reviews has obtained the AX5670 1GBD5-NS3H which has been modified from the HD 5670 reference design to include an extra 512MB of memory as well as reduce power consumption. This review will test the lofty goals set by PowerColor as well as reveal the truth about going green.

When first released and tested, the reference HD 5670 consistently under-performed close competitors like NVIDIA's 9800GT. As a result the 5670 was initially priced to closer to the GTS 240. Since that time the price on the 9800GT has dropped into a competitive range. Part of the performance anemia in the reference design may be due to ATI's stance on RAM. It has been consistently claimed that 512MB of memory is enough to support computations. Yet third parties like PowerColor consistently bolster the reference design by adding more and faster memory. In the case of the Go! Green AX5670 only the quantity was increased, possibly in hopes to step above the limitations of the reference design and close the gap on the competition. Another smart move by PowerColor was choosing reference cards with already low power consumption to performance ratios and making them even better.

The Go! Green claim is to reduce power consumption the HD 5750 model with a result of halving the 584 kgs of carbon dioxide emitted from a video card in a year. The most obvious change is the use of a passive GPU cooler rather than a fan. As they say on their site, "Silence is Green." Does this claim hold true for their HD 5670? Two great decisions by PowerColor poise the card to have impressive results, but the numbers and graphs will tell the real story.

# Power consumption and heat testingMatt 2010-05-14 12:34
I am a little sad that in the review the Powercolor NON-Go! Green 5670 card wasn't compared to its Go! Green sibling. This would have been a much more valid test to compare actual temperatures and power consumptions. Not that it doesn't seem like the Go! Green 5670 power consumption savings numbers seem a bit inflated, but it still isn't a very validating test (at least of the Go! Green 5750 it seems like the power consumption numbers do seem to be about 25% lower than an actual side-by-side tested 5750 (non-Go! Green) based on a benchmark of that card).

Final comment is on the design (owning a Go! Green 5570), fanless? Sure quieter, but a 1w silent fan could probably save 2-3w on a low power card and 5-8w on a high draw card by reducing temperatures 10-15c. My 5570 benchmarks in my case at 56c using furmark and with a 1.4w 80mm held up against it drops to 35c stable (21c drop). That has gotta be worth a few watts through better electrical efficiency running 21c cooler.

My video card has the same type of residue as that card, and it quit working after two years.

What brand and model was it?
Can you tell us more about the failure mode?

My computer came with a nvidia 9800 Gt. Since about a week ago I have been unable to play a video game or use windows media center. If I ever start a video game or windows media center the program crashes and I get the error message, "nvlddmkm.sys has stopped responding and has recovered." Some times I get A blue screen message and the computer has to restart. I have reinstalled drivers and even restored my computer's software to the original factory condition. About a year ago I noticed my computer screen would get dark, as if i was wearing sunglasses. I would restart my computer and the screen would look normal again. I replaced my video card and found white layers of crusty residue.
