Power, Temperatures and Noise
How To Write A High School Application You Didn#39t Graduate As with the Radeon 6900/7900 series and GTX 500 series the 600 series performs power management in a different way to older cards. In fact the GTX 680 even more so than the others which means we have changed the way we test power and temperature levels in our reviews. For idle power we list the full system use at the wall after sitting at the desktop with no activity for 5 minutes. Load power is the highest reading we saw for the full system when testing during this review. Temperatures are taken in the same way. Noise levels are taken after a period of prolonged gaming in a scenario which applied maximum load to the GPU.

When we move to load the card does draw more power than the reference model although it runs cooler and quieter (up to 9dB) while also outperforming the reference 7970 on these fronts.

In the first image we can tweak the power available to the card as well as the core/memory speed offset to overclock, more on that shortly. In the second image we can see the graphs which show the power draw and speeds as we open and ran 3DMark 11. The three key results are the top items with the first line showing the power use of the card, the second the clock speed that the GTX 680 set itself to and the third our memory speed which varies less.
Taking the technology a step further we have the aforementioned power/speed controls. By increasing the power available to the card and the speed used as our GPU/Memory offset we can overclock the maximum speed of the card. In the first graph we have the power/speed lines shown for a Battlefield 3 session, the second graph is a continuation where we applied a 132% setting to power and approx. 100MHz on GPU and Memory over the stock settings. Following the change in settings the GPU speed registers as 1197MHz (rather than 1097MHz in graph1) and memory as 3110MHz compared to 3005MHz. Of course the fluctuation in the speeds will depend on the game played and how much power it requires.
