Power Draw. Its importance.

Same old, same old. It was a massive issue when fermi was released and a lot of you posting it doesn't matter in here would have been all over it. You just flip flop the argument to suit.

What I care about is heat, more watts is more heat(and noise). My ref 290X was a nightmare in the summer months(as was my GTX480 when I had that). I want a cool running card, not bothered about what it costs to run etc.

This is where performance per watt has got its traction from. As long as the card performs well, at a reasonable temp that has a reasonable powerdraw then its all good. Couldn't care if its 1.5x or 2 times performance per watt i care about the FPS i can get and if i got overclocking room with temp and power draw. Along with the noise it generates. I dont look at its performance per watt LMAO.

Contradicting your self a little here, you don't care about PPW but do care about getting the absolute highest frame rate from the package, they go hand in hand with one another. Saying something is 1.5x or 2x the PPW is as good as saying it has the potential to be 1.5x or 2x faster.

This is why people were getting excited about 'big maxwell' as early as the 750Ti, for a 60w card it was very quick, people made rough calculations, scaling that up into the magic 250-300w area and seeing the potential. The PPW laid a marker of what was to come in terms of overall GPU performance.

Again to flip this another way, the AMD Nano is boasting a relatively tiny 175w TDP yet is 2x the PPW over hawaii, so we know future architecture improvements, even on 28nm will give huge gains over Hawaii.

as someone has already said above... GPU's have a "budget" of between 250W and 300W for maximum performance, if the perf/w is higher for the same budget then absolute performance is higher for a given product

you care about performance. Manufacturers, system builders and OEM's care about not having cards that go much if at all over 250W, how much performance they can get in to that form factor has a direct relationship with perf/watt

Agreed :)
 
Noise! My old 7970/7990 setup was so loud the mrs couldn't hear the TV and would moan at me. I'd cap games to 30fps just to reduce the noise.

My current rig is much quieter.
 
I imagine it's simply easier to improve on efficiency now than to improve on pure performance, similar to how it is for CPUs, not to mention it has more implications for other areas than just PCs.
 
Not contradicting my self at all as a consumer I don't care bout performance per watt at all. Manufacturers do etc to get more performance out of their cards but why does performance per watt have any interest to me? I care about performance! Ppl banging on about cards which use slightly less power and perform about the same as other cards is just silly.
 
It's a non issue tbh. Those that hailed the gtx980 are now running 980ti and Titan X which are high power cards. The FuryX looks to run somewhere around the same watts if not slightly higher at 275w. If the performance is there then power usage seems to be fine and a decent cooler should always manage the temperatures. If you have a decent case nothing on the market should cause you trouble.

If cards tend to limit the power envelope to 250-300w then PPW should be #1 on list. If it wasn't, AMD wouldn't be trying to increase efficiency.
Whatever floats your boat though.

As some one pointed out to me many of times, Your not limited on the power envelope certain Titan users told me they could draw well over 400 watts on thier cards.

Like i said when i'm looking for a card i don't look at its PPW i look at benches and look at the FPS it gets, i look at price, i look at what temps it runs at, overclocking potential. One thing i've never looked at is the PPW at all. I couldn't care less if it was 1.5x more efficient than last gen. Or if it uses 30 watts less power than a competing card.

This is something that matters to the manufacturer as they have to worry about the power envelope etc. I don't produce the cards just buy them. I care less about Performance pew watt.

Performance pew watt only become a big thing when first maxwell chips came out (970 and 980) when all thier buyers and nvidiots kept banging on how great they are because they use a lot less power. Id rather buy a card that gives me the same performance at a lower price. Even if it does use more power. Power is on the bottom of my list as a consumer.


Also now the nano is doing something similar it seems, its not a big deal coming from the people who went from 980/970 to titan x or Ti lol.

Some people use a single PSU to run each titan because it draws so much power :o ;)

Whether you deny it or not, PPW is something that matters to you, otherwise you'll be running 1500w single core graphics cards just to get todays performance. That wont be cool running or have any oc potential.

No still dont care about PPW, if the card was drawing that much power heat is what concerns me here. and cooling, then noise. If cooling it was too much trouble i would look for alternatives. And you just blew that out of context by well over exaggerating things.


Were talking about what the the people who bigged up PPW on the 900 series like it was such a important factor when considering a GPU and that is obviously not the case.
 
If there was two cards A and B and they both performed the same in games. But A had 1.5x PPW vs B, would this bother me that much? no! however if B was slightly cheaper which would i opt for? B obviously because PPW doesn't matter.
 
The efficiency of maxwell is what allowed the TX and 980ti to come out offering double performance of the 780/titan using the same power draw. Yes, PPW is nothing to talk about.

What was the 970 TDP? 160w and trades with the 300w 290x, yup PPW is worthless to talk about.
 
Nobody cared about even the midrange Fermi cards having worst power draw than the HD5000 and most of the HD6000 series since Fermi had better tessellation and it was worth the increased power consumption supposedly. Its all swings and roundabouts.

I am sure next year each company will have some new selling points they want to market to the masses.

Is the efficiency of the 290x what has let the fury x become what it has?

the 390x beats the 980 more often than not with a worse PPW and its essentially a 290x which had worse PPW than the 980 and now the 390x beats it so that made your argument irrelevant.

PPW is at the bottom of the list to be cared about as gamers its just what certain nVidia peeps hyped up to be something when its nothing.
 
Hot damn, 390x trades with a 980 and uses 100w more. That's something to brag about. Psst, 980ti rapes and still uses less.

I'm sure you'll change your tune come Fury(X) considering AMD themselves big up the efficiency improvements.

Like how your throw your dummy out of the pram when i make my point.
Also its not 100 watts more little over exaggerated there. All that is, is just power saving features that make it look good. And i'm not bragging about anything just making a point. And i already know how AMD have made their PPW better by looking at the nano. It beats the 970 and possibly 980 in performance and uses a lot less power. Do i care? no

All i care about is performance and price mainly. Second comes overclock potential and noise it generates.

I'm waiting on Fury x and its performance and by looks of things beats the 980Ti and still couldnt care less if it used more power than a 980Ti.

But from what Gibbo said when he used one in a rig.

Gibbo said:
A stock it's quite power efficient and if you use the FPS target then power rarely exceeds 200W.

Hi there

Also happy to report absolute zero coil whine and pretty much zero noise, never seen it go above 40c under load. :)

Performance I can't hint to simply as that would land me into trouble but it's faster than my 290X which was clocked at 1100/6000. :)

You might be interested in the Fury x if PPW is something that interests you?
