    Seems like the name is causing some issues here: First it's "SU" and then "Du" instead of "Su"
    ;-)

    AMD is comparing with Nvidia P instead of V, on the CPU side you rock but GPUS? Sorry folks

    Well, that's a bit unfair. You can't compare against something that doesn't exist. Volta may have been announced, has many "here's what it can do" pages but there is no physical product yet.

    As an aside, we don't really know how powerful this GPU is but it's supposedly the world's fastest accelerator, which suggests it's faster than P100 in some tasks, and more importantly they believe it is noticeably more power efficient. When was the last time Radeon was more power efficient? Plus, the gaming versions are hinted to be faster than Frontier and will likely have higher clockrates than MI25, too.

    Now that I've defended this, it is time to confess I am also disappointed that there aren't more examples of MI25 outperforming Pascal somehow.

    Agreed. Only way AMD could have legitimate comparisons against Volta would be if they had insider, pre-release access to NVidia's future hardware. So err, yeah.

    AMD have been noticeably picky and cagey about pre-release benchmark publications lately.

    That said, we know the TDP and it's equal to that of the Tesla P100, and we know they're claiming it's ~10% more powerful than P100, so there's fairly decent ballpark figures. As far as compute goes, it's easier to predict relative performance anyway; it'll certainly be competitive with, if not outright outperforming Pascal.
