Matches what RTG said in the reddit AMA. I wouldn't even call it a rumor at this point.
I expect Nvidia will have something of similar performance in the few months following that. I doubt any of the first wave cards will be much faster then what we have already -- just more efficient.

That seems like wishful thinking, im sure Maxwell had similar efficiency claims.
I'm looking to build a bedroom PC in the next few months, might pick something up from this range, get me back checking out AMD stuff while still having the confort zone of the main Nvidia setup.

Micron has not said it's in volume production, they've said that they've started shipping samples to customers, and expect to start volume production during summer.

Very interesting! AMDs first solid product in a while that I'm curious about. On a side note. Use spell check man (srping?). And you said "HBM2 based product no sooner then early 2017" - "then" should be "than."
@Denial may be right about the first wave of these AMD cards, they may not surpass the Furys and 980 Tis.

And it makes sense. On a new process when yields are crappy, having a giant die just going to drive the cost per chip way up. Nvidia can justify it with the GP100 because it's going into a $100,000+ box where companies don't think twice about spending $15,000+ per GPU because it's still way cheaper than the alternative.
In gaming though, that additional manufacturing cost would turn a normally priced $650 chip into a $2000 one. Very few gamers would actually buy it. Most people would just complain. That and Nvidia would have no product for next year. So they are better off reaping the high margins off GP100 units in the compute/HPC area and just doing a half size chip for gamers that's normally priced.
Well I think AMD does want large GPUs, they just don't like to lead with them.
In fact Anandtech wrote an article about their "Small Die Strategy" all the way back in 2008.

Can't wait! Go AMD, GO!

PC Perspective.
They want to invest in fast, small, good yield dies and scale them using an interposer instead of making a huge die. He's even speaking about "beyond crossfire", where they give that as a default configuration. Judging by their roadmap this will come with Vega.
A lot of things have changed since 2008. I believe that if they are cornered performance-wise, they would most likely make another big die. But read the article and listen to his interview at Lane

I want to sell my 2x390X
Definitely crossfire and SLI are so fkng bad...
Looking for a beast single GPU I hope AMD makes another FuryX Polaris

Nice one bring it on AMD , let's hope it delivers this time and i am actually looking forward to this release. Crossing my fingers that it will be a good overclocker 😀

I have heard that 7 nm might be the wall. If true, we will be very close to it soon ... especially with 10 nm soon.

That's not even to mention that Knights Hill is launching on 10nm in 2018 and it's ~700mm2.
Regardless, even if it is 2019, it's still 2.5 years instead of 4.5 and you still have all cost reduction issues (well lack of them). These nodes aren't getting cheaper, they are getting more expensive. It makes sense for AMD to just avoid it by making smaller chips.
I'm also not sure how you think they will get near 100% yields out of that. The chips themselves will have a yield rate, the interposer will have a yield rate (although at 65nm it's probably really high) and the stacking/melding process itself will have a yield rate. I'm also not sure how the thermals would work out. The surface area would increase but the total power requirement would also increase as there are longer routes and extra connections. Plus what's the maximum size of an interposer? Just seems like a lot of added complexity that would be unnecessary if yields were good, but again, they probably won't be, so I see why AMD would go that route.
Intel's 14nm is also on a whole different level then any other fabs and the specs on their 10nm is even better.

I hope amd will win major marketshare back, nvidia needs serious ass kicking

Sounds promising but Im still switching back to Nvidia.
