Lisa Su confirms Q3 launch for Ryzen, Epyc and NAVI
On an Annual Stockholders Meeting yesterday AMDs Lisa Su reconfirmed Q3 for Ryzen 3rd gen, Epyc Rome and NAVI. Q3 means from July to September. That's what, the second or third confirmation?
So once again we see a confirmation for the products to be released pretty soon, which would be the second half of this year is going to be busy with three separate product launches. AMD will soon come up with more details likely on the Computex keynote, after which there will be a "Next Horizon Gaming" live stream during the E3 gaming conference on 10 June. The products themselves will then released and on the shelves after July at the earliest.

That's baseless. AMD can't really add more transistors to GCN because only way to do it is to make CUs beefier. (As they can't put more than 64CUs there due to design limits in logic.)
If GCN could have 96CUs, they would just decrease clock by 10%, reduce voltage appropriately to lower max clock and be at same power draw as now. And it would still be smaller GPU than nVidia's counterpart that it would compete with while having much better compute than it already has.
(Here you can say that AMD made unbelievably shortsighted choice. Their 1st GCN chip already had 32CUs, that's 1/2 of maximum.)
You continue to miss the point. My point this entire time is that AMD can't add more transistors. It's design is too inefficient. That is AMD's entire problem. That is why AMD is so far behind.

I'm afraid it doesn't work that way, as a quick glance at any perf/watt chart from a techpowerup review will clearly show you. AMD would need 400w at a minimum to make exactly what you described.

Same way as any other AMD's GPU being sold at unreasonably clock and voltage.
According to TPU database Fury nano is just 10% slower (1080p) than Fury X while Nano has 175W TDP and tiny cooler and Fury X has 300W TDP and integrated liquid cooling.
Same way as I was able to reduce power draw of any AMD's GCN card by good 25~30% with minimal performance loss or gain if I tuned memory timings and clock.
Sacrificing clock and reduced voltage will get you very far. Have you ever seen AMD's Zen based APUs with Vega iGPU? Looks like you did not. Kind of funny if you look at their performance at 15/35/65/95W. There's really not that big of an difference.

Ahh, of course, the ol "undervolting is an AMD only feature" argument. ignoring the fact that literally all semiconductors behave the same way, and that the reason they all mostly run at higher volts than they need, is because there are always a few that can't. AMD owners are just obsessed with it due to their dumpster tier efficiency at stock settings. Both of my 1080ti's will do 1800mhz at 800mv. Undervolting is not AMD specific.

Although to be fair, compared to how much AMD cards ship with a higher voltages than needed compared to Nvidia is quite high to the point where if you have an AMD gpu you almost have to tune the voltage for it to be reasonable. Nvidia cards out the box IMO at least have reasonable voltages where you do not need to tune them at all.
Not sure how undervolting is on Turing, but at least with cards like the Radeon VII can be undervolted to be competitive in power draw compared to the competition.

After making such post, I would have think that you already know voltage requirements and current increase for reaching last 5~10% of achievable clock. So, why it is so hard for you to understand that actual downclock of 10% on GPU which can't be really overclocked more than 5% yields quite different results than undervolting nVidia's GPU which can be OCed by 15% or more.
