    Bleeding edge as in foundry stuff.
    The what.
    You only have so much time and manpower to make your shrinks actually be worthwhile.
    You don't even consider risky shit a-la 7LPP here.
    Yeah
    G6X is not even a JEDEC thing made for nV duties exclusively.
    Those things were always ovens.
    What changes was product positioning and die chops, aka the things that change all the time.

    You don't say.

    The plan. P-L-A-N.

    What shrinks bro? Sidetracking and strawmanning again?

    Yeah, because everyone and Nvidia especially likes furnaces. Because they shed a good light on your engineering and sell like... hotcakes.

    Ok, bro, let's see if I got this right, let me just quote your arguments for reference:
     
    Benetanegia, HLJ, DegustatoR and 2 others like this.

    Yeah but 104 chop would still sell gangbusters.
    Oh it did a lot.
    In general we had a lot of SKU shuffling around.
     
  4. The 2080 Ti is a TU102 GPU that started at $1000. A fair comparison should be the 2080 non-ti here.

    It's possible that Nvidia planned for the GA104 to succeed TU104, GA102 to succeed TU102, i.e., having the full GA104 (3070 Ti) to succeed full TU104 (2080 Super) as RTX 3080 but at a respectable ~35% faster;
    With the RX 6800 XT and 6900 XT, they may have had to promote the 3080 to a GA102, and at the same time demote the Ampere Titan RTX to the 3090.

    There are some big signs pointing to the 3090 being planned as a Titan card: lots of VRAM, ridiculously large and expensive cooler, over-engineered PCB, power consumption through the roof, etc.

    I doubt Nvidia planned from the beginning to sell the 24GB G6X 3090 for just $1500 when they had been selling the GA102 Titan RTX with 24GB G6 for $2500 the year before. That should be reason enough to suspect they did some reshuffling at the high-end.
    And the only thing that changed between 2018 and 2020 was that this time AMD had a competitor at that performance range, in the form of Navi 21.


    Why would you fail to quote my last post that refers to the original source from a taiwanese financial news website, which was posted a whole 6 hours before yours?

    It’s extremely unlikely that they planned to ship perfect GA104 dies in volume at series launch. A theoretical GA104 based 3080 would’ve sold well enough but would have been received far less positively given the meagre improvement over the 2080 Ti.

    The actual 3080 is a 30% improvement over the 2080 Ti which makes it a lot more attractive proposition. Ampere was competing with Turing far more than Navi.

    The SKU scramble post initial launch was likely a response to Navi 21 but those were rounding error moves and didn’t change the overall stack much at all.

    Tbh 8LPP yields are like super nice.
    It was competing with Pascal/Maxwell grandpas clinging to their good things.
     
  7. The RTX 2080 was a 9% boost over the 1080Ti.
    The GTX 980 was a 5% boost over the 780 Ti.

    A GA104 3080 would be completely fine if it brought a 10% boost over the 2080 Ti.


    Doesn't need to be perfect. Take away a couple of SMs like they did for RTX 2080 TU104 and the performance difference would be negligible.
    By "full" I meant not taking away >8 SMs and some PHYs or slower memory that brings performance down by more than a notch (e.g. 1080 > 1070).

    EDIT: a word.
