NEW STUDY: Taming the Energy Use of Gaming Computers

[Bensemus]

i7 4820k to pentium G3258... What?

[vXhanz]

That's nice and all, but it's a drop in the bucket compared to AC/Heating for a house. Not to mention all the devices that when left plugged in have a "trickle" charge like TV boxes, cell phone chargers, clocks, etc. The only way to really "stop" power bleeding out of the house is to flip the breaker on the main. 

[Glenwing]

Trying to scare people with big numbers...? In a global context, those numbers aren't terrible. Let's flip it around, 160 million refrigerators (I'm sure there's at least that many, globally) use more power than all the gaming PCs in the world... that's a lot of power! If we all went out and bought the newest super-efficient refrigerator, we could save billions annually! Of course, billions of dollars split among all the people in the world is... a few dollars per person. Per year. So, not as big a deal as it sounds.

I have the TVA where i live, power is cheap, mostly dams and coal plants. Some of the best in america I hear. 

drop in hat compared to a car or heating and air. 

^hats are dlc only

Shit!

 

Imagine how much it would use under load...

 

I kid

 

Underload? About 300w for normal gaming. I was trying to see how far that thing could overclock. +170mV  made the card use much more power. 

[Minzo]

I didn't buy a powerful machine and expected it to draw low power.

[Guest trucker2]

ever notice no one studies how much electricity is used by CNN or PMSNBC

[Keystone Nyan Cat]

How did they carry out this study? If possible, can the OP kindly include this please? 

 

Edit- we have to buy to know this apparently; until I actually see their test methodology, I doubt I will accept any of these claims

[Blebekblebek]

how is this news?

Isn't this obvious?

regular computer only use 50-100w without GPU

 

add GPU it adds 50-300w under full load.

 

however, no one took a study over how much AC consume power daily? or heater?

[Xaring]

So much bullshit. They are using a "crappy" CPU, it can't compare to the previous one.. (I7 to Pentium) 

 

Ive been studying computer engennering for a couple of years now, let me tell you that the performance of the second one wont be as good as the other , oh well, guess you dont need to be a genius to realise it.

[Bittenfleax]

Ehhh... just worked it out (not sure if it is accurate). But if I have my PC on 10 hours a day (on Weekends and about 6 hours on weekdays) it would be around £100 - £150 a year and average UK electricity prices for West Midlands (where I live). That is baring in mind I used 500w not 750w because my PC is not always at load.

[vXhanz]

Did I miss something in this? I see "hours per day" on the bottom of the chart, is he saying 24 hour full load operation?

Hmm, the newest generation of parts is more energy efficient than several generations ago. So to make a more power efficient computer, I should be constantly upgrading! Who cares about the more harmful waste created by all these non-recyclable parts. At least we're saving more energy every year, right?

[deviant88]

Ok give me 50% gtx 960-970 subventions and price cuts and ill upgrade from my gtx  670, oh wait it uses similar power, gtfo.

"just by swapping some component, you'll get almost same performance lower  power draw"

[zappian]

House appliances consume much more .

 

Electric heaters go up to 3 thousand wats and refrigerators are on for much longer than any gaming pc.

[Dabombinable]

Lmfao, my rig may use more power than my old 'gaming' (think low end Pentium III) rig, however the performance per watt is far better and it uses only around 500W of power, if not less.

 

Edit: I also have solar power and my console is an Original Xbox with its stock 100W PSU (I haven't needed a new ATX PSU for it yet-and yes it works with one).

[You_are_a_cunt]

A pointless study that could have been easily confirmed by looking at my electricity bills :]

[linuxfan66]

i still think the gpu market is out of control power usage wise. it used to be much lower power draw even on high end gpus. now...not so much. 

gaming cpus are still varely power efficient in default mode and work without requiring overclocking(providing your not an amd fx).

my two cents anyway

[ObeseWalrus]

My power comes from wind farms, I don't really care.

[Thony]

Well dont blame the users, blame the manufacturers for making the global heaters

Also give us money to buy every top end and latest component everytime it comes out so we can reduce the energy consumption.

Stupid study.

[ShadowCaptain]

Fuck the planet, im too busy Fulton extracting sheep in MGS V

[QueenDemetria]

As someone who uses AMD FX and Nvidia Fermi, how dare you say I use too much power.

 

My power comes from wind farms, I don't really care.

Me too I'd like to do solar someday too.

[KamiKatze]

What were those guys thinking???

 

"hmmmm, how in the world can we save some energy? Replace regular light bulbs with power saving ones? Improve house isolation to keep thermal energy inside the building? naaaaaw! let's rip on gaming PCs!!!"
