There is some implications though for how far you can push performance before cooling is an issue.
All the indications seem to point at GF being 6 months behind TSMC in terms of maturity of the equivalent processes and Samsung also seems more optimised for the efficiency of smaller cores than making big high performance cores - however I suspect AMD will slightly less drip feed performance with upcoming stuff than nVidia has done.

Come on then, lets get AMD to release a bigger chip than Polaris to match the 1070/80 now (that would also use GDDR5, with HBM2 not being available yet), so we can see how it sells compared, baring in mind how expensive its going to have to be be, due to the monster cooling it would need, and the sheer amount of power it'll suck, as it would need Hinkley Point.
Me, id take the cheaper/smaller 1070/80 all day long over it, that i could probably just blow on myself to keep cool, and only have to use a potatoe to power.

I don't think the problem with HBM2 will be cost.
Remember the Fiji cards are quite cheap compared to a GTX 1080.
I think there are problems with HBM that both AMD and NVidia are aware of that is making it's roll out on gaming cards very slow.
As to power saving I also think that is nowhere near as good as claimed. Remember GP100 based cards use a lot of power compared to gaming cards.
I just looked at a RX480 strix OC review, according to the techpowerup review, the RX480 strix is approx same power consumption as a reference 1080.... and only approx 55% of the performance... so it is not looking that great for the vega cards etc. I would say 2 generations behind is not wrong.. nvidia are almost double the performance per watt currently.

The concern of consumers is absolutely irreverent in the discussion absolutely architectural efficiency.
All fine and well saying that, however polaris 10 is effectively a laptop card frequency scaled up near it's limits. You can ignore the power consumption but the hardware can't ignore the current draw, this is what amd defence teamboys are failing to grasp. The raised 50 power limit along with the variance in the silicon quality will only get you so far on air,
1350-1400 ish. In the real world the gains are 5-12fps over a non throttling 1266mhz. To then purchase a block and pump and then use a modded bios that fools the i2c power draw you then have to ask yourself why go to all that expense when a competitor has a better performing card for the same if not cheaper and at less/similar power consumption but providing more performance.
From my observations on my own custom cooled rx470 ref board I can use 1.175v to get me upto 1360-1380 with temps at peak 60c but the power draw is so high that in actual benchmarks and some games the performance is not scaling past the sweet spot of 1300mhz at 1.08v +50 power limit. In firestrike it won't hold 1360-1380 all the time as it's the card which is power limiting So then back to the original ''Ohh power doesn't matter'' well yes it does actually.
Like I predicted in the Fiji thread, Amd can't just rely on a die shrink to gain their ppw, they need to address dx11 scheduling and dx12 and the front end.
If Vega is just Polaris 10 scaled up by x2, just like Fiji was over tonga, then it's obvious where vega will perform.
So let's hope it's another tweaked gcn, but with Amd's R&d budget I can't see it happening.

But makes all the difference when it comes to a point scoring debate, which is pretty much the only place where it "matters". Some people on here would be on the whinge if an amd card used 5 more watts than an nvidia equivalent and spin it as a massive negative, yet if the same were true for team green that would be quickly brushed under the carpet. Gets old, fast.

I think if I had to use either a 1060 or 480 for gaming it would probably be the Polaris card.
I don't have any solid reasons for this but just find the 480 more likable.
This post has no scientific basis along with nearly every other post in this thread.

But if AMD produced a card that was 25% faster than a TX but used 50% more power nobody would really care. Unfortunately at the moment AMD released cards such as the 480 much later than NVidia's latest offerings and cannot match performance or efficiency. And a slower card using more power than a faster card sux.
Amd have been here before though with the 2900xt, they'll bounce back eventually.

No they wouldn't, but a card that is much slower, using more power, and is hotter, is an absolute joke, Polaris is just embarrassing.
Its clear they're light years behind Nvidia.

Hm well that would be 375w TDP, that would definitely need AIO watercooling, also I have a 500w oil radiator that I use in winter, it can heat a whole room in about 30 mins... so that small GPU in PC would be almost the same as a 500w oil radiatior.

Why are we talking about Polaris in a Vega thread? Polaris is just a die shrunk Tonga, 380X.
Vega is a brand new architecture, Polaris has nothing to do with anything Vega.

Well it is the only thing that you can use to guess, there is no information or benchmarks of Vega.. But judging from the performance / watt etc. of polaris, which is the only info available, it is not looking great.
