AMD Moving to 12nm Vega and Ryzen in 2018
AMD’s CTO Mark Papermaster shares word that AMD will be moving from the Global Foundries 14nm LPP FinFET process to a new 12nm LP process in 2018. Global Foundries announced that 12LP will begin production in 1Q18.
The news reaches us through Toms Hardware who confirmed that the company will transition both Vega GPUs and the Ryzen line of processors to the 12nm LP process. They however are not sure if he meant that 12nm LP will be a shrink of Ryzen in 2018 and/or if Zen+/Zen 2 will also be using the 12LP process. The question rises as AMD implied that Zen 2 would use the 7nm process. The company has used both "Zen+" and "Zen 2" to refer to its next-generation die.

Very nice I hope they can do more with Vega being on 12nm but I doubt it'll make any noticeable difference. I can't help but feel like they would have been better off using a core with around 3000 shaders and 2 stacks hbm2 just going on gamers nexus comparisons.

Isn't Vega already using 2 stacks of HBM2? Or perhaps you meant 4 x2 instead of the current 2 x4 design to reach the 8 GB capacity the consumer version currently has.
Shaders are a interesting one too, similar to the Fury versus Fury X GPU's there doesn't seem to be a major difference between the 64 and 56 which from my understanding of it after having read around a little bit about the subject the cards are being bottlenecked in other areas instead thus the Vega 56 when bios modded to remove some of their other limits actually do really well.
If there was a tool to allow locking and unlocking these clusters or cores it would have been really interesting to see just how far down one could take the GPU before performance was seriously impacted and how much headroom this would in turn allow for overclocking due to thermals and power usage dropping down, perhaps if disabling 8 of them (64 -> 56) gives some headroom then more could allow for the GPU to compensate by clock speed instead and perhaps see greater gains from that, eh perhaps it would hit some other limitation instead and at one point reducing these cores would start affecting performance too but there might have been some room for fine tuning things. (Perhaps later on bios modding could have some interesting possibilities depending on how things go.)

WHY NOT 10NM OR 7 NM
SAMSUNG HAVE IN 2018 7 NM

Seems like 12nm lpp is an extention of 14nm lpp, much like tsmc's 12nm ffn is to 16nm ff, appears the intent is to move stuff from 14nmlpp , it specifically mentions it minimizes redesign cost from 14nmlpp.
