Instead of a thousand words.

In short:

4096 streaming processors.
4GB HBM RAM with over 500GB/sec bandwidth.
Core: 1GHz
RAM: 1.25GHz
TSMC: 20nm (kinda implausible)
 
What makes you think that's the new GPU?
..and Why is it being tested on a Crosshair IV?
It doesn't make much sense to me.
 
AMD needs to pull a rabbit out of their hat; I want to see some power efficiency or I'm going to Nvidia :shadedshu:

Very peculiar indeed, I am interested to see a little more information about this because these choices seem to be different from what I was expecting.

Power efficiency says the person running 2x R9 290's

All the more reason for people like him to complain about AMD's power efficiency.
 
Is power efficiency with AMD really that bad? How much us$ per month difference in electrical bill compared with using Nvidia card?
 
I dont care about the electricity bill, i just use it, thats what its there fore. I never turn off my machines, and some lights never go dark, i couldnt care less. Lets say the difference was 100 kilowatt a year, it wouldnt bother me at all, I would use the saved power on some other gadget instead, who cares.

It depends on where in the USA you live and how many cards you're running but to answer your question in general. If your AMD card was using 150 watts more than the Nvidia equivalent card. The average cost in the US for a kWh is 12 cents. If you game for an average of 20 hours a week then your monthly electric bill is going to go up ~$1.56

So, not much.

Good thing the industry does. Lower power processing requirements are currently driving most new developments - everything is about power reduction as portability becomes more and more relevant. But this is irrelevant, this topic is rumour - as much as the Titan II one is on the news section of TPU. There's nothing in this OP that suggests anything about power draw - we don't know what architecture it is. This could be more efficient than Hawaii - we don't know.

Let's hope the 390x is a Maxwell killer - otherwise we're facing more hideous prices from Nvidia's top range.

The powerconsumption itself usually isn't the problem. The results for a system when it comes to cooling, noise, space and powerdelivery however are usually more significant.

If this card has higher powerdraw, but also uses an all-in-one cooling solution then AMD trades in worse powerdelivery and space characteristics for better cooling, noise and presumably performance. Imho that isn't a bad trade-off to make when you're at the limits of what you can currently do technology and architecture wise.

Regarding electricity costs vs poweruse: unless you're a really hardcore gamer who does little else on his/her PC, idle poweruse is way more important than load poweruse. AMD has traditionally done quite well for single monitor idle powerconsumption, but multimonitor and media consumption have done worse.

I don't think it is the cost difference of a higher powered card that people care about... it's the heat and noise levels to deal with.

edit: as Mathragh posted at the same time
 
Indeed, I also prefer my room not to become a sauna when I game.
 
The power efficiency comes into play when you run your card(s) quite often. Since my aim has been geared toward crunching and folding, power has become a concern for me.

Running my CPU and gpus 24/7 adds up quickly, pulling about ~550+ watts, and that's just one rig. So yes, power is a concern but not really for mere gaming. If gaming were my only concern, I wouldn't be worried at all.


Thus, I would like to see AMD do better on their power efficiency on the cards, as many others would too.
 
I like how everyone forgets about Zero Core...

Is good for long idle only. Doesn't help when you are in 3d applications or gaming. But again - 390x has no mention of power usage so any discussion of energy usage is speculation - which has been thrashed to death.
 
Keep cool, keep all the power....

Still saving power tho isn't it? NV has nothing even close. It doesn't take that long to kick in either.
 
So, what you're saying by the specs is that I gotta have it?

You'd be damn right. Nvidia can eat a dong. I stuck a 660ti in a buddie's build b/c it was cheap and it's pretty sad (stuttering and crashes). Nvidia drivers are shit for older games. Works fine on new games. I see where their priority is (benchmarks).

Well that's the usual of discussions regarding the 390X at all:
Person 1: Hey did you hear about the (Insert new rumor), sounds cool right and could be nice for the new 390X?
Person 2: Yea but the 290X uses electricity and was a bit hotter which is all that matters.
Person 1: But what does that have to do with the 390X, is that relevant?

Thus the conversation goes on to be an off topic discussion when that happens.

Well Zero Core is for idle and kicks in making power usage very minimal which is very obvious and works. Nvidia does however have an equivalent which makes them all pretty much on par.

Keep cool, keep all the power....

Dude we get it your a fanboy and obviously do not care about the 390X so you can stop.

Yep but some places have really high electricity especially some countries which have more than triple normal costs in the U.S. which could factor in so I can understand some of what said (Though at that point my argument is why get a high end card if your that concerned because obviously your money could be used better elsewhere).

I am with you on that, better efficiency also is great for the mobile market which could mean better laptop GPU's among other devices.

Just pointing out AMD care about power consumption, no need to get your knickers in a twist sweetness.

Although they are clearly full of shit too.

Yeah, I know. I have seen someone say they pay 40 cents per kWh in a European country iirc. I was just responding to the guy who asked how much US $ it would cost.

They care as much as Nvidia does.
The roles currently seem the reverse of what they were when that video came out however. Back then you had the GTX480 which for its time used lots of power while AMD had the 5870 which was comparable in performance and was 1,5 times as powerefficient on the same process.
AMD back then made use of the situation by producing that video. This time around Nvidia seems to refrain from stuff like that however, while also lowering the prices of their card way more than they'd have to based on product positioning and demand.
 
Can't we discuss AMD, Nvidia, power, etc without insults and name calling?

Boy I regret my initial comment in this thread :oops:

I know you knew and was speaking specifically at that person I was just making a general comment.

Yep but the problem is what people view as important in the moment which reverses quite often.

I have to say though the 390X only having 4gb of ram maybe a little disappointing to me as I was hoping for more but then again the new compression method makes all previous ram amounts bigger which could be pretty nice either way. I do hope power consumption goes down but ill take heavy performance numbers especially at high resolutions over super low efficiency for my needs (Though I would prefer both to come in one package).
