    If it taped out in march, it's at least 3-4 months before the silicon comes back and another ~6-12 months before product.

    Earlier, 1 year from Tapeout till Sale is normal. As probably the big HPC chip taped out first, add 3 months to it, so May-June for HPC Ampere.
    But the smaller chips coming after shouldn't need more than 1 year and will probably get released in a similar timeframe.

    You're thinking "semi-conducted" would have been more appropriate ?

    I think it's highly appropriate for Ampere. :)

    Just to point out that they didn't actually confirm wether all of their 7nm will come from Samsung or just some, they've used Samsung before too at least for GP107

    I think the GP108 (used in the very popular MX150) is also made on Samsung.

    In the meanwhile, I've been seeing reports saying that TSMC's vanilla 7nm have just gotten a "free" 10% performance upgrade, and that process' yields have jumped significantly.
    If 7nm DUV became so good, it makes me wonder what's the point with 7nm+ and 6nm.

    Yep
    or is that "free 10 performance upgrade" really the '6nm'?

    It's TSMC's 2nd gen 7nm.

    I got it wrong though, it's reportedly over 5% and not 10%.

    https://fuse.wikichip.org/news/2408...ls-2nd-gen-7nm-and-the-snapdragon-855-dtco/2/



    Still the difference to 6nm will now be smaller and 7nm DUV yields are said to be really high, on the level of 16FF+.

    6nm uses a number of EUV layers.
    This 2nd gen 7nm is DUV only.

    BTW, TSMC is now claiming that 7nm is cheaper than 16nm, in cost per transistor.
    Again, this is 7nm DUV. We're not into EUV territory yet.

    Not much of a cost improvement though. And given transistor counts are increasing much faster than density is improving there's only one direction for end consumer prices to go.

    Very skeptical about this claim. And it doesn't take into account the huge increase in design cost and mask set

    true, but it´s Bits and Chips so take it with the same relevance as WCCFTECH :nope:

    Whoever wrote the tweet didn't author the graphs nor TSMC's claims.

    Do we even know if Ampere is a successor to Volta or Turing? I don’t think NVIDIA has ever indicated.

    I hope it’s for consumer and not enterprise. I hope they at least double RTX performance.
