    Interesting slide on the cost per mm^2 in the slide. Likely why NV didn't use 7 nm, and why they may wait longer than most people expect to use 7 nm for the consumer market. The current NV is really focused on high margins and 7 nm would currently eat into that.

    The jump in cost from 14 nm to 7 nm is quite significantly larger than any previous node transition it looks like.

    I'm not sure if NAVI offers enough competition to convince them to sacrifice margin to go to a significantly more costly node.

    It remains to be seen if NV feel threatened by RDNA 2 coming next year.

    Nvidia will go 7nm but with Samsung

    https://www.extremetech.com/gaming/294441-nvidia-will-team-up-with-samsung-for-7nm-gpu-technology

    https://semiwiki.com/semiconductor-manufacturers/samsung-foundry/7926-samsung-vs-tsmc-7nm-update/

    And from here it seems Samsung has the best wafer price of the market

    "Unrestrained: Radeon RX 5700 XT overclocked to over 2.2GHz. Break the limits with the new SoftPowerPlayTables for the RX 5700 and RX 5700 XT"

    "The power and resulting power consumption for the entire graphics card and all of its rails is now also evident in the detail graphics. The relevant for the power supply spikes with 10 to 20 ms in length are about 300 to 320 watts, which is therefore also to be taken into account. Everything about it is not relevant, since it is way too short to trigger a shutdown."

    AIB cards and 5800-5900 should be interesting to see, this overclock was done with watercooling. Sadly Igor is only presenting data from one game.

    So, looking at that, sometime at the end of next year at the earliest maybe. Looks like Samsung are desperate to get customers for their 7 nm node since they are late compared to TSMC, so NV might be getting good pricing from them. The drawback, of course, is that it may be quite a while before NVs first 7 nm GPUs come out.

    Didn't TSMC say somewhere that cost per transistor is already lower than 16FF and yields would reach parity by the end of the year? That should put making the same chip about the same price on either process

    Yet another site making conclusions by taking things out of context.
    NVIDIA did confirm they would use Samsung 7nm, true, but they never said they wouldn't use TSMC 7nm or 7nm+. They even clarified later that TSMC continues to be important partner to them.
    NVIDIA has previously used both Samsung and TSMC within same gen, too.

    Edit: also, NVIDIA 7nm production at Samsung is apparently scheduled to start 2020

    To be fair, the bolded part would still be true if NVIDIA went exclusively with Samsung on 7nm, since TSMC is currently making all of their 12nm parts, and most (all?) of their 16/14nm chips as well.

    That's cost per xtor, and 7nm dies tend to have many more of these in general.
    For something the size of Navi10, yes.
    nV's flagships are usually way bigger.

    True, but my point was that one shouldn't draw conclusions from the "we're going to use Samsung 7nm" announcement regarding what NVIDIA does or doesn't do with TSMC
    Of course, point being that at this time at least price shouldn't be the reason to stick to older process anymore, even if you changed nothing else you'd get lower consumption etc without affecting the price
    Well they said "big dies", didn't refer to any specific size, could be Navi10 size, could be bigger.

    Samsung late on 7nm ? Yes and no because, unlike TSMC, the Korean giant decided to skip 7nm DUV and go directly to 7nm EUV. So if we compare 7nm EUV, they are less than 3 months apart on volume production, with the advantage of higher density for Samsung.

    For the Hardware Unboxed RIS video the tl;dw is that they're very impressed with the result when downscaling a 4k to around 1700-1800p and applying the sharpening filter. In many cases the result was equal to or better than DLSS in several titles with basically no perf loss. Especially when it can be applied to any game immediately rather than having integration by developers then weeks/months of training.

    No discussion in video about affect on UI or other aspects of the game and obviously more in-depth analysis by several parties is needed.

    Im pretty sure nvidia confirmed that their next gen cards will be built on tsmc's 7nm.

    This is going to be extremely useful in the console space..

    ?? Because AMD want's to sell Navi cards? Simple as that. CAS (which is what RIS is) works on GCN and Nvidia GPUs when implemented in game (Rage 2 or any other game or engine who decides to add support for it) but the "free for all" driver option is currently a Navi only feature.
