NVIDIA GeForce GTX 680 Review: Kepler Debuts

22 thumbs up

Before bringing this article to a close, we'd like to cover a few final data points--namely power consumption and noise. Throughout all of our benchmarking and testing, we monitored acoustics and tracked how much power our test system was consuming using a power meter. Our goal was to give you an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power drawn by the graphics cards alone.

Total System Power Consumption
Tested at the Outlet

The new GeForce GTX 680 proved to be quite power friendly under both idle and load conditions. With the GeForce GTX 680 idling at the Windows desktop (with the monitor displaying an image) out test machine consumed only 122 watts—11 watts fewer than the GeForce GTX 580 and 5 watts fewer than the Radeon HD 7970.

With the GeForce GTX 680 loaded up, our test system’s power consumption jumped up to only 358 watts, which was among the lowest of the bunch. When running under load conditions, the GeForce GTX 680 consumed 46 fewer watts than the GeForce GTX 580 and 17 fewer watts than the Radeon HD 7970. That’s a big win for NVIDIA after years of more power efficient AMD GPUs.

With the improvements made to the GeForce GTX 680’s PCB and cooling hardware and the power efficiencies inherent to the architecture, it should come as no surprise that the GeForce GTX 680 runs relatively cool and quiet. Our particular card idled at about 42’C and peaked at about 73’C under load according to EVGA’s Precision utility.

Noise was also a non-issue. At idle, the GeForce GTX 680 is essentially silent and couldn’t be heard above the noise produced by our CPU cooler and PSU. Under load, the card’s fan did spin up to audible levels, but we would not consider the card loud by any means.

I was looking to do an upgrade to this but the price and the fact I need a mobo upgrade (actually whole system) as well pulled me away. I would of done it if I wasn't heading to college next year and I'm going to get a laptop.

Great performance from this card. I have been looking forward to the benchmarks and I am not surprised. Metro 2033 is going to be a tough cookie for some time; but everything looks really solid. Great review Marco :)

Thanks, man. Killer card for sure.

Yeah the Nvidia prices especially on debut are very high. I was a member at this website last year that did these great give aways pretty often. I was hoping to see them do more give away contest's but they quit I guess as I have not seen any more since last year. The point is I was looking forward to trying to win a system (I could really use one for work and home) with one of these as I cannot really afford it right now. Oh well maybe some other great site will do a contest like that I sure hope so!

Great Review Marco, this card is a beast. I have to agree with @LBowen, the benchmarks aren't that surprising and neither is the price. You have to pay to play and Nvidia knows it! I'm happy to see the power consumption and temp results, they are heading in the right direction! No cooking eggs on this card! Looking forward to seeing it in full production and oc'd to the max.

Just out of curiosity I would love to see how this card performed with video and 3d rendering, and yes I understand it's a gaming card not a workstation card.

Thanks for that hella nice review. Big Green just gave AMD a slap in the face with lower prices and more performance. I can't wait to get my hands on one of these beautiful cards. It will be really interesting to see what the manufacturers come out with for non-reference cards.

Yikes...great job NVIDIA. AMD could afford to launch their cards at the exorbitant $599 precisely because NVIDIA hadn't struck yet. Now that Kepler's in town, watch those prices drop.

Gee, AMD can't catch a break, can they? Well it was a fun 3 months or so...

Looks like the Green machine is back on top,huh? Well I guess they deserve a turn, since it's been awhile.

Let the price wars commence!
