    Well, aside from the 225W vs 300W.
    I only see a reference to Vega 10 and an X2 product in a dual GPU card??

    Opps! My bad I had read the 2nd ones as Vega 11! My eyes just saw 1st and 2nd so automatically assumes Vega 10/11.
    x2 so a HD295 type thing
    So there's nothing on them slides about Vega 11 then aside from the roadmap / product positioning. Which shows Navi similarly going X2 for that segment.
    For compute this might make a lot of sense, but for gaming Crossfire/SLI have been doing rather badly. And more direct APIs like DX12/Vulkan mean that the game devs have to do even more of the work. Can't see that working too well...
    ...Unless AMD somehow manage to get a dual-GPU design into a console.
    Maybe there is some way that they could design a chip to allow two to be stackable on a monster HBM-like interposer. Assuming this 450mm², times two is already 900mm² plus 4 stacks of HBM2. Would be monster chip but if the HBM2 was in the middle in a rectangular design, might this make it easier to cool?

    Looks like Linus managed to look at the Vega 10 prototype!

    Here is a better picture:

    Its an engineering card,and the extended PCB part with a USB3.0 port is for monitoring purposes - but it does seem Vega10 might be air cooled,since it seems weird an engineering card would have a lighted logo on it. It makes me wonder if it is a prototype of the stock cooler is being used??

    I'd put money on it. No point giving the engineering development card a different cooler to the one used in final production. They mention power monitoring - at lower temperatures power consumption goes down, so with a water cooler you can't directly compare power consumption

    It might hint that Vega10 won't be as expensive as something like a Fury X too??
