With the death of TSMC's 20 nm, AMD only has the 14 nm of GloFo/Samsung left, but Nvidia is moving there, too.
Will the 300-series be that much better than the 900-series? Maybe. But will it crush GM200?
AMD is the best sub-300 dollar offering. On 1440p, according to computer base's performance index, the 290X is a mere 9.5% behind the 980.
AMD's drivers are now de facto better than Nvidia's.
But all of this is because they have to be better. We are moving towards a monopoly in the GPU market which would mean slower progress and higher prices. The next time you have a VRAM scandal, there won't be an alternative to turn to. And that isn't good for anyone except Nvidia's bottom line.
AMD's Lisa Su has the background to pull this off, because AMD's problem in recent years that they had too many non-technical people in leadership positions(hello - and goodbye - John Byrne!) and a lot of their past CEOs weren't that smart, to be brutally honest. Lisa is the first AMD CEO in a long time to match and possibly exceed the deep technical expertise of Jen-Hsun.
Time will tell if that is enough, but at least its a strong step in the right direction.
I continue to hope that Intel jumps into the dGPU space. If Intel has branched out into SSDs they can do the same for dGPUs. They are investing a lot more into graphics technology these days anyway, both for their integrated stuff as well as for their mobile SoCs. The jump wouldn't be as large as it would, say, 5 years ago.
