GeForce GTX 670 2 GB Review: Is It Already Time To Forget GTX 680?

Power Consumption

At idle, GeForce GTX 670 is just 1 W of system power behind AMD’s efficient Radeon HD 7950, and just 1 W ahead of the GeForce GTX 680. The older Fermi-based GeForce GTX 580 uses an additional 13 W, and the dual-GPU boards are significantly more power-hungry, even when they aren’t doing anything.

AMD’s ZeroCore suite of technologies enables additional savings once our host machine’s operating system puts its attached display to sleep. Shaving off more than 10 W gives both of the Radeon HD 7900-series cards a lead here, while the GeForce GTX 670 and 680 shed very little power at all.

Nvidia claims a typical board power of 141 W—about 30 W less than the GeForce GTX 680’s typical power rating. A quick run through 3DMark’s Deep Sea and Temple demos allows us to chart system power use, where we see the GeForce GTX 670 using slightly more power than AMD’s Radeon HD 7950, less than the GeForce GTX 680, and significantly less than a Radeon HD 7970. The GTX 580 is there to show that even AMD’s flagship is a more efficient choice than last generation’s most compelling options.

Averaging out system power use doesn’t yield worst-case consumption numbers, but it is a more realistic look at gaming over time.

Truly, the GeForce GTX 670 looks pretty sharp, using just slightly more power than Radeon HD 7950—a card it easily outperforms. The Radeon HD 7970 it closely competes against averages more than 50 W higher.

    I really think AMD should of set the 7970 clocks higher at default. Any 7970 owner knows with their card at 1125/1575 its much faster than the GTX 670 but this review paints a very different picture.

    Shut up and take my money, NVIDIA!

    AMD probably have very good reasons for keeping their cards at that level. I mean, if they could release them factory overclocked, they would be doing it as fast as they could, as it would give them a huge edge.

    gtx 670 and 680 performance is too similar !!!!! 680 is pointless !!!! don't buy it !!!

    Great job with the relative performance % charts on page 15 - would be great to start seeing this in all graphics card reviews (for example the upcoming GTX660 review comparing with GTX570 and GTX670!). Also good job re-running the numbers on all three GTX600 cards with the fresh drivers.

    You should be aware though when talking about availability issues that these don't necessarily apply to all markets. Over the past couple of years (since GTX470/GTX480) launch, I've observed quite a few cards with apparently poor availability actually being very easy to get hold of in the UK. Maybe it's easier to cater to the graphics needs of 60 million people than of 300 million :-) Something to keep in mind anyway.
