Energy Consumption Stats

anyone know of a place to look at the latest video card energy use stats.
seems like all the ones I can find are pretty outdated don't have any of the new cards on them.

Currently have an 8800GT in a 1920x1080 win7 desktop setup and looking to go more energy smart. I don't game... PC is really only used for browsing, blurays, and of course porn. 😛

AMD currently has the best idle power draw (what you will be seeing if you wont be gaming much)
 
thanks for the nfo guys!
wikipedia pulls thru again! hehe

my buddy says getting a sandy bridge cpu + mobo and use onboard video might be another solution.. expensive but very energy friendly.

Sandy Bridge is about ~95w TPD rateing...

you could find a smaller cpu, mix with a tiny dedicated gpu, and have less power used than the sandy bridge. If all you do is web browseing ect, that ll probably be cheaper than buying a sandy brigde and you ll probably get higher grafics performance from a cheap discrete card.


**edit: you could get a apu like the LLano, and have a total TPD of like 25w ^-^ or something small like a Zacate, I belive those go down to like 9w-18w TPD (depending on cores/speed of cores).

Just for reference, I have a G31 chipset with an E5300 CPU undervolted to .9v and clocked at 2Ghz. The idle power draw is around 17-20 watts from the wall and load (P95) was 33-35 watts. Streaming Netflix sat around 20-23 watts. Single HDD W/on-board video and sound, two 120mm antec fans on lowest setting and a mini LCD (HTPC thingy) and Windows Vista Ultimate

Again, simply amazed at what a microATX board can do when undervolted and underclocked.

For another reference point, I have a Dell System that has an Intel 1.6Ghz E1200 also with G31, one 80mm case fan, three Hard Drives and that pulls 40 watts in idle, and 70-80watts under load. The Dell BIOS does not allow me to undervolt, unfortunately. Which means I may end up migrating my server to combine it with my HTPC. It may save me a good 40-50 watts of 24/7 use, which actually is a decent amount of money over the year. Though I am not one of those penny pinchers when it comes to that, it just seems to make sense.

FYI- TDP is rather meaningless number. It stands for Thermal Design Power and is a guide to MFGs for building systems to dissipate that amount of heat. Very rarely does Intel exceed its TDP, AMD on the other hand... That isn't AMD hate either... 😀

TDP is a fully loaded figure. Sitting on a web page reading, the CPU will be SIGNIFICANTLY below TDP. Sandy Bridge is very good at idle power.
 
For a discreet card an ATI HD 5450 is very power efficient.

If you want to go with a new build and don't game a Clarksdale i3 5xx would be good for a budget build. Just use the integrated Intel HD graphics.

If you want some more CPU horsepower go with Sandy Bridge i7 2xxx and use the integrated graphics. Either build will be energy efficient.

People might forget about harddrives... getting a Solid state HD could lower power comsumption a fair bit as well.

And ram... DDR3 usually use abit less than DDR2's.


@Concillian, so are the zacates ^-^
