The point I was making in the video is that AMD could have released a card to compete with GP104. It could have had HBM, possibly even HBM2, and it could have cost the same as what the GTX 1080 is gonna cost (think north of $600).
It would have been faster, but most of you would still have bought the 1080 instead. This has been seen time and time again in the past with cards like the 560 Ti vs the 6950 and the 460 vs the 6850. Both times where AMD was faster yet completely outsold anyway. The 460 outsold the 6850 by 4-1.
AMD is a company out to make money. Nvidia is too and they make more money by selling to their high-end buyers over and over. 680, 690, Titan, 780, 780 Ti, Titan Z, 980, Titan X, 980 Ti...now the 1080 another 25% faster than the 980 Ti.
People just keep lapping up those 30% increases at more $$$ but that's a market that will eventually run out of legs. It's unsustainable.
Nvidia is bottlenecked by wafer allocation at TSMC so they have to pick and choose which cards get made first. Those gigantic P100 Teslas at $10K a piece are way ahead of any gamer GPU and using up wafers like nobodies business. AMD will gain a lot of market share in mobile while Nvidia does this, it's really very simple strategy.
