No. TSMC has 2 variants of 7 nm, one meant for mobile (used by A12, Kirin, Snapdragon etc) and one meant for high performance (used by Zen 2, Vega 20, Navi and future NVIDIA chips etc). Mobile chips don't eat HPC allocations and vice versaand there won't be 7nm Vega for gaming this year either. TSMC 7nm production will be occupied by A12, Kirin 980, and Snapdragon 855, then later Zen 2 silicons. Reason why Vega 20 is going to be released on limited quantity later this year (which may or may not happen).

Surely with processes this complex it's not just about flipping a switch on the product line, I'm quite confident they're completely separate to push out bothAre you sure about that? I mean, they have two processes, but don't they share equipment or production lines?

And significantly higher clocks on TSMC 7nm compared to GF 14LPP.Vega 64 with 1:2 double precision, additional deep learning instructions and interconnect.
Nothing of this is particularly gamey.
Where do those 35% come from?You also could build one being 35% faster and you could build one, that's twice as efficient.
I doubt they'd make a gaming Vega 20 with 4 stacks.Does 32GB VRAM, half-rate FP64 or external IO links sound anything like "gamer stuff"?
And significantly higher clocks on TSMC 7nm compared to GF 14LPP.
A Vega 10 clocked 30% higher than 1.5GHz (~2.0GHz) would perform at the same level as a 1080Ti or 2080.
I saw it in an AMDs slide labelled „Leading Edge 7nm Process Technology“ here: https://www.tomshardware.com/news/amd-7nm-gpu-vega-gaming,37228.htmlWhere do those 35% come from?
I see 30% claimed by TSMC compared to 16FF+, but Vega 10 isn't made on that process. It's made on GF's 14LPP which according to various statements ( from @Nebuchadnezzar et al) is some 10-20% worse than TSMC's 16FF+.
So we're looking at ~45% to 55% higher clocks on Vega 20, at ISO power.
But while it's likely that Vega missed its frequency / performance targets, pretty sure consistently hitting > 25 % higher clocks also involve some redesign to the basic shader units. I'm willing to bet AMD didn't commit resources for this, given their statements so far and the target market
We should further expect from professionally oriented GPUs to be clocked very conservatively. Pure performance is just one variable in the many determining the products' success (viability rather, it's 2018 RTG we're talking bout). They've increased bandwidth, hugely beefed up the FP64 part, increased VRAM significantly. And they cannot change the software ecosystem overnight.
If they'd be binning chips to squeeze an extra 10-20 % shader performance, they'd be throwing alot of otherwise good chips away. All that to change just one variable
That presentation is previous to GF dropping 7nm, so the 35% could be an average of the gains between the GF and TSMC's 7nm nodes over the current 14LPP.I saw it in an AMDs slide labelled „Leading Edge 7nm Process Technology“ here: https://www.tomshardware.com/news/amd-7nm-gpu-vega-gaming,37228.html
Still need to figure out the primitive shader front end which could give a substantial boost in addition to clocks. If that allowed scaling to multiple chips, a viable part could be made with Turing's MSRP. Boosting throughput in addition to scaling wider with higher clocks would be inline with the Epyc strategy and be competitive if they got it working.A Vega 10 clocked 30% higher than 1.5GHz (~2.0GHz) would perform at the same level as a 1080Ti or 2080.
They don't have to use the same clocks for every SKU. The workstation Vega 10 cards (FE, WX9100, SSG) have different clock settings compared to the RX Vega 64.
That presentation is previous to GF dropping 7nm, so the 35% could be an average of the gains between the GF and TSMC's 7nm nodes over the current 14LPP.
They also don't mention if it's for turbo or base clocks.
Still, assuming those slides refer to a Pro version then we should compare them to the WX9100 with a 1500 MHz clock. 1.35 * 1.5 = 2025 MHz.
This press release from AMD after GloFo announced their exit out of 7nm for now seems to indicate that AMD was either well aware of GloFos plans in advance or that they had planned initial 7nm products for TSMC fabrication anyway. So it would make little sense to include a purely hypothetical figure into their forecasts, lowering expectations or sandbagging.That presentation is previous to GF dropping 7nm, so the 35% could be an average of the gains between the GF and TSMC's 7nm nodes over the current 14LPP.

I don't care either way anyway, since I have no stock in either AMD or their competition.
That^ entire video is on point and covers my exact thoughts on AMD's direction.
I already predicted as much this past week. Chen already said a year ago, that VEGA's HBCC can already use any type of memory or storage type. (GDDR5/6/HBM/DDR4/SSD/etc..) And given AMD's 7nm leverage & all the plausible rumors... I can easily see a 7nm Radeon V96 & V128 @ $550 bucks, out for Holiday shopping season. With the average GPU performance 8~12% higher than the RTX2080 and using less power. (win/win)
AMD will have 7 months reign in sales, before Nvidia can respond with their 7nm chips in Aug next year...
What would you like to bet, since all this can “easily” happen?
- Radeon Vega with 96 and 128 CUs
- $550 price point
- Available between Thanksgiving and Christmas 2018
- 8-12% higher performance than 2080
- Lower power consumption than 2080
