Gaming Performance & Power Usage with Half Life 2: Episode 1
For some reason the Intel 975X platform fell notably behind the P965 and nForce 570 SLI, which will surely hurt it in the performance per watt comparison.
Power consumption is fairly consistant, with the nForce 570 SLI drawing 6% more power than the Intel P965 while offering similar performance. The performance per watt chart below summarizes that fact fairly succinctly:
As we crank up the resolution the performance gap narrows, making all three platforms virtually equal.
Power consumption actually stayed virtually unchanged with the 570 SLI drawing 5.9% more power than the P965.

3 of the best Motherboards you can get, all i think with the extra-stable 8 phase power - and you have 'em all in one line-up.
Can i work at Anandtech ? :-)

(even when disabled these parts likely take some power)8steve8 - Thursday, October 12, 2006 - link
im curious, what about g965 with onboard video...also , i think u should have used more minimalistic boards... otherwise the power could be drained on the additional features like wifi or a 2nd nic card or whathaveyou

It's interesting to see the diffrent between chipsets. The chipsets seems to have started t use quite a bit of power. Hopefully you will be able to do more detailed test some time in the futire, load on diffrent rails and so on.Lonyo - Thursday, October 12, 2006 - link
The HL2 640x480 numbers for the 975 look really wrong (198 fps vs ~230 for the other 2 chipsets).Anonymous Freak - Thursday, October 12, 2006 - link
You'd need to test the power consumption of multiple brands of motherboard using the same chipset. This could just be an Asus thing. (After all, the Intel chipset boards are "Deluxe" while the nVidia chipset board isn't. Maybe they actually spent engineering efford to cut down on power draw on the Deluxe boards.)Also, for a review interested in power consumption, I'd like to see comparisons not just with a dedicated video card, but also with the integrated video of appropriate chipsets. For example, I play almost no games, and actually WOULD like to save as much energy as possible. What motherboard/CPU/GPU combo will give me the best media encoding performance bang per watt? (A Via nano ITX board probably would win in performance per watt, but with unacceptably low performance.)

All this tells me is that Asus's P965 mobo uses less than their 975X and 570 SLI mobos. It'd be better to compare across brands (using the same chipsets available from each brand.) Then you verify your result.atenza - Thursday, October 12, 2006 - link
Am I the only one interested in idle consumption of those systems?mongo lloyd - Friday, October 13, 2006 - link
Me too. Most computers, especially the ones that are running 24/7 (which is more and more prevalent today), are idle for a guesstimate of about 90% of the time. Really.I was disappointed in this article as well, because they really should've taken that into regard (and made it the most important thing as well).

No, I am interested as well. My computer is kept in a relatively enclosed space. My P4 used to be completely quiet before this, and now is loud b/c the fans are spinning a lot faster. Of course I am not looking to keep the P4, but I am planning on upgrading soon. This basically let me know what I wanted to know and it becomes a no brainer in chipset choice for my application. Here I can get the less expensive chipset and still save on power. I am carefully choosing all of my components for my next build. I want as much integrated as possible and do things like have only 1 optical drive and go down from 3 HDD to 2 etc. (And of course get a cpu that uses less power.) Now for the person who said that a few watt doesn't mean anything, if you get a few watts out of 5 coponents that is a significant power savings for the system as a whole.Josh
