    Going from 7P to 7+ should net them 20% power gain at best so it's still another 30% to cover with architectural changes. Quite a lot considering that it was way less than that between GCN@7 and RDNA@7P.

    That's from vanilla 7 to 7+.
    It's like 7% for 7p to 7+.

    You're right, it's about 5% between 7P and 7+. So even a taller order to hit these +50% with RDNA2 then. Will be interesting to see how it will work out for them.

    Very well.
    They didn't seed those Zen mgmt people into RTG just because.
    Navi3x series will also kick ass, since it has specific partner-derived goal.

    Zen3 and Navi3x might offer some nice performance.

    Seems likely, but remains to be seen. Hopefully, AMD will be able to do more than just compete with 2080 Ti (a then >2 year old product) in the enthusiast space.

    Well, let's hope that this will be the case. It's long time overdue for AMD GPUs to fight NV on perf/watt again.

    They're fighting QC and Apple now too.

    Navi3X is being accelerated to meet targets of a well known Handset manufacturer.

    Bingo!
    And you know what Samsung wants of their sub-6W peak sub-4W sustained flagship part.

    Well that's a funny assed mixup, probably should've been expected at some point since "+" is just such a vague, overused marketing signifier.

    Guess this means Zen 3 and RDNA2 could be on N7P or even 6nm for the former, depending on when it comes out. Makes financial sense too, taping out EUV stuff as such is supposed to be really, really expensive, and it's not like 7nm+ actually gave almost any improvement (hence why almost no one used it).

    Edit- They also pretty much confirmed Arcturus is their separate, Vega derived compute GPU. It's all compute concentrated and even, apparently, cuts graphics parts for it. They're officially splitting it into "CDNA", and since it doesn't computer graphics specifically one wonders if "GPU" is totally a good acronym anymore.

    Anyway, I suppose one should split it off into its own thread since it's official and not RDNA.

    I thought vega20 and navi10 were on the same node.

    If Vega 20 is N7P then they are, but not sure if it's ever been confirmed which Vega 20 is

    edit:
    Not sure if it was mentioned already, but Navi2X support DXR 1.1, AFAIK there's no confirmation yet whether Turing does that too or is it limited to 1.0

    Hu, I was expecting some benchs/numbers. They just said "yeah it's coming".
    I get it was for investors, but still...

    Nothing about Mesh Shaders or Tensor Cores?

    Tensor cores was hinted at for CDNA, likely will be a server only feature.

    Apparently, the Ray Tracing demo shown at the event was a pre recorded video as well.
