[Ars] System Guide special: it's easy being green

Video cards

The easiest way to conserve power is to go with integrated video. This is the lowest-performance option, but for office users, casual browsing, and pure 2D use, it's more than adequate—and well worth saving the 10W, 20W, or even 35W from a discrete video card. Motherboards spitting out integrated video via DVI or HDMI aren't that hard to find, so power-users with their massive LCDs don't have to suffer.

Gamers and other users who demand decent 3D performance will probably find the best combination of low power and performance with the AMD Radeon HD 3850, which draws only 13.5W at idle, or the Radeon HD 3870 at 18.7W—compared to 34.6W of the NVIDIA 8800 GT 512MB. Powering the hundreds of millions of transistors inside a modern NVIDIA G92 or AMD RV670 GPU doesn't come cheaply compared to the vastly more simple and much more modestly performing graphics cores built into motherboard chipsets.

The idle power consumption for HD 38x0 series cards is really impressive... The extreme green box they cooked up is pretty interesting too, <100W @ load.

Considering I pay 15.5¢ a kWh I may have to go "green" @ some point.

What a load of hogwash. This whole "green" thing is getting on my nerves now. Talk about the biggest marketing hype ever made.

I couldn't care less even if I had to chuck trees into my PC to keep it running.

... otherwise nice find though

Yeah, no doubt "green" is part of a huge marketing scheme... But many of the parts labeled green truly offer superior efficiencies/power ratings. For example WD GP hardrives and Intels new SFF CPU line-up. Admittedly, the term green annoys me to no end, however if the products live up to the hype so be it.

You could underclock the CPU and GPU, make them even better.

Some of those power specs look sketchy though, 31W for a loaded E8400? And 10 times the draw for a writing CDRW as opposed to a seeking HDD?

That actually looks about right.... Optical drives are about 20-35w while HDDs are under 10w. Newer HDs are even lower.

Tech Report reports the Intel Core 2 Duo E4300/G965 and AMD Athlon64 X2 BE-2350/690G combination are within 5W at idle and 4W at load, which is almost indistinguishable.
a typo.. hehe

We don't need to be green. The only advantages here are less electricity means less energy, meaning less heat, and the fact that you'll save tiny amounts on your energy bill.

Electricity is not a bad source of energy (burning fossil fuels to get it is, but only because we are running out. CO2 has nothing to do with CAUSING global warming kids. Global warming causes CO2 rises. Human activity has nothing to do with it. Don't believe the media) - using nuclear/wind/geothermic/hydroelectric/solar/etc... generation is just fine.

dendrophilia? I'm not a "tree-hugger", yet I do wish to lower my power consumption as that tends to save me some jack... But to each their own.

My city utilities company is a Co-op, so our juice cost me 15.5¢/kWh, I'm sorry I don't share your pugnacious attitude. Perhaps if mommy and daddy still paid my bills I too would piss in the wind.

Actually no, that was the load for the "green gamer"

The one I was referring to can be found on pg.6
