aren't graphics cards power efficient enough?

[SAV1OUR]

well with nvidia pushing power efficient gpus couldnt you argue that they are already efficient enough? you can run a damn 780ti and a 550w psu and OC thats efficient to me, are we looking at any benefits with the 800 cards? because you relay dont need to go any lower in power supplies in my opinion whats your thoughts on this?    

[qwertywarrior]

what do u exactly mean by power efficient

power efficient compared to what at what task

[zapsyou]

They're doing it for laptops and smaller form factors so that we don't have to have massive towers, it's the same as what intel is doing.

[Paralectic]

More effiency is less heat so that will make cards more powerful because they can be pushed way more far.

[Marvzl1357]

I don't think so, like everything cutting edge, you're looking to be as efficient as possible. It's not a matter of decreasing your power supply needs, but being able to fit more with what your power supply is already delivering.

Also heat is a large factor.

For someone who dreams to live completely self sufficient and off the power grid by using wind and solar no nothing is ever power efficient enough and why is it so bad you are saving money on your power bill.

 

P.S power is expensive in Australia just like everything else lol

[FloRolf]

you are never power efficient enough

Well, if you look at the fact that high end GPU's still need beefy coolers on them to keep the temperature down, they're still incredibly inefficient, with a lot of the power they consume just being output as heat.

I think that idea vanished with the first nuclear bomb.

That's one of my aspirations! Good luck on your self sufficiency venture!

Power Efficiency lowers power consumption, heat output and increases longevity and durability of the GPU making it ideal for OC.

It's all perspective. Imagine if in some alternate universe the "average" power supply was around 300W instead of ~500W and you could run a 780ti off 300W. If someone came out with a graphics card that meant you needed a 500W PSU there would be complaints about inefficiency.

Something being more efficient is never a bad thing.

I want to see a high end gaming rig with no moving parts(fans). This means passive cooled CPU, GPU and PSU. All SSD based storage. No case fans. It will take some time to become a reality, but how cool would it be.

[Humbug]

well it's all relative isn't it. There are no absolute. Our GPUs are very power efficient compared to What they were 4 years ago. But in a few years time the performance/watt of these parts will look bad compared to what's on the market.

Nope they are still nowhere near power efficient enough. just try gaming on a laptop battery and watch how quickly they run out of juice...

Zalman has a passive CPU cooler. PowerColor has a passive-cooled R9 270.

You will still need some case fans; if you are using a passive cooled PSU as well. (Silverstone has one.)

What I hope nvidia does now is when a new architecture comes out, they try to make it as efficient as possible. IE 800 series. But on that architectures last year IE 900 series. Make the card as ridiculously powerful as that architecture can be. I would buy a new high end gpu every 4 years and stagger that with a new cpu motherboard config. So if i was to buy a 900 series card, I would be buying a new CPU/ mobo this summer. That way it's cost efficient while being a powerful computer. Efficiency isn't a big deal to me to be honest.

[nj4ck]

less power = less heat output. there is no such thing as "efficient enough".

[Clarkey]

Just look at some of the overclocks people are getting with the 750ti. I havent seen a review yet where they didnt manage to get it to at least 1200mhz and not substantiated but there was a forum post about someone getting one to 1700mhz.

 

Given a couple more years making maxwell better we could be seeing much higher performance out of the same number of cudacores.

[deafboy]

Absolutely not.

 

One thing I hate about gaming laptops is that you pretty much HAVE to be plugged into the wall to get the most out of the system.  Also, more heat output to deal with.

 

Efficiency FTW.  It's the one thing that is still pretty interesting when it comes to GPU tech.

[TriBeard]

IMO, For the most part, they are efficient enough in that most people can run a high end card at relatively low noise levels (assuming a decent cooler) in a variety of enclosures. Basically, the power envelope that they sit in currently is ok to me. However, if you can make them more efficient, you can cram more shaders/transistors/good stuff in that same power evelope and get more performance for your wattage. That's how I think efficiency should be used to help us. I personally don't care much about the 750Ti or whatever other cards come out that are low power, accepatble performance cards. Sure, they have a place and I'm not saying they shouldn't exist. I just have no real interest in them. What I want to see is about 4 of those GPUS's on one die (not in sli, just a single chip with 4x the shaders, memory bandwith, etc). That sounds like a good time to me.

i think they are. they need to make more cards with bigger cores and more stream processor/ cuda cores now a 1000w single gpu would be beast!
