It is official AMD skips 20nm and jumps to 14nm
Although this was a rumor for a long time now we now know that AMD skips 20nm and jumps onto a 14nm fabrication node for their 2016 GPUs. Yields in the 20nm have been a massive failure and as such many manufacturers are skipping that 20nm node.
The AMD Radeon 2016 line-up tagged under code-name Arctic islands as such will jump straight towards 14nm FinFET technology with stacked graphics memory dubbed HBM. as expreview reports. A huge jump considering the current products are still at 28nm. What this means is a smaller die and lower voltages. E.g. a Hawaii GPU would be precisely half the size of what it currently is.
Currently Intel and Samsung are the only nodes that can offer 14 nm production, so it will be interesting to see where the wafers will be baked. For example, Intel is manufacturing "Broadwell" CPUs on 14nm and Samsung is manufacturing the Exynos 7 SoCs on 14nm.
It will be interesting to see how the lineup of 2015 shapes up to be, but expect 28nm parts.
AMD Greenland will be the R9 400 Series Flagship in 2016.
From that new lineup, the Greenland GPU would be AMD’s first GPU to be built on the 14nm likely fabbed by Gloablfoundries. It would be the flagship GPU dubbed the R9 400 series which will be tied to second generation High Bandwidth Memory (stacked memory).

They are either going to end up using TSMC's 16nmFF+ or Samsung's 14nm.
Most likely they will go with TSMC. Also don't be confused by the 1xnm difference, you can't compare the numbers directly anymore with the 3D transistors. Both processes are very similar in terms of density and power.
But yeah, TSMC's 16nmFF+ for GPU's is already in risk production, with full production set for November. So 16nm Nvidia GPU's will probably be ready to go by March 2016.
Edit: I should also point out that this is the exact reason why I would not buy a GPU this year.
The gap in performance should be pretty hefty with the move from 28, to 16/14FF. Although it's going to be complicated for Nvidia, who will be moving from GDDR5 to HBM, slightly refined architecture and 16nm all in one product. If they screw it up, then that's going to be AMD's chance to catch up, since they should have already worked out the HBM/interposer kinks with the 390x.
As I'm not really familiar with the chip manufacturing business, could nvidia move to Intel to get something with 16nm or even 14nm manufactured?

I plan to get just one, as long as it doubles HD7970 performance which is quite probable.
As it will allow me to use 1440p with reasonable fps.
Come on your on 7970 upgrade to 390x and you get huge leap in performance.
At some point you can safely upgrade in your case it seems a good deal 7970 to 390x is huge step.

Yeah baby, I really hope that this time AMD is going to steal a lot of land from nvidia. I'm usually fan of neither and I'll go with whoever has better product BUT I don't wont to see AMD dead so this time I really want to help them out.
My 670 is way to slow for my 1600p resolution so maybe for the time being before AMD's 400 I'll go with 980ti when it comes out and then swap it, it all depends on 390x what it shows.
It's a shame this ain't easier so they could jump right to 10nm to get ahead of nvidia even more.

I agree vg24a3. I would buy an AMD card in a shot to help them out but only if performance was there. I don't understand these ridiculous people that are brand centric.

Intel generally don't manufacture chips for other companies so they can keep their advantage of having smaller nodes before most others to themselves.
Not sure how good intel's fabs would be at making very large die/transistor chips such as gpu's since the cpu's are generally much smaller. Would be very powerful for NVidia if it ever happened though.
