Encoding Performance & Power Usage with DivX/WME9
In our DivX encoding test there's about a 10% gap between the Intel 975X and NVIDIA's nForce 570 SLI, with the P965 falling in line closer to its older brother than NVIDIA's offering.
Power consumption is as expected, with the P965 consuming the least and the nForce 570 SLI consuming the most.
The performance per watt chart has the 975X and P965 tied, thanks to the 975X's higher performance. And given the nForce 570 SLI's lower performance and higher power consumption, it falls to the bottom of the chart.
Windows Media Encoding has all three platforms equal in performance:
...and power consumption is very similar to our DivX test:

Whoops. Intuitive logic doesn't always pay off. See the following chart which gives energy costs/BTU for 2006: http://www.npga.org/i4a/pages/index.cfm?pageid=914">DOE Energy Costs . You can see that energy cost from electricity is almost double that of natural gas. You may help heat the building, but it will cost you more. And remember that a lot of electricity comes from coal fired power plants (CO2 producing) and every wire consumes it's own share of energy released as useless heat. Ok probably too much off the chipset topic, sorry.DigitalFreak - Thursday, October 12, 2006 - link
Quick, call Al Gore!Thanks for the good laugh.

10w is not all that inconsiderable, look at it over multiple components and it becomes significant.10w just for the mobo is, IMO, quite a chunk.

Could you measure the power draw of just the chipset by increasing the voltage of the northbridge by 0.2V and then re-running the tests? Take the difference between +0.2V and normal and then you would have isolated the power draw for the chipset and can work out the power draw for the chipset alone.
