    Has there been any news about when, or even if, nvidia RTX 20xx Super cards will come to laptops? Any rumors? Any educated guesses?

    I don’t think they will come to laptops. The Super cards have increased TDP, and Nvidia seems pretty set on keeping the TDP of mobile Turing low.

    Given there is a headroom limit to the cooling and power in laptops that has already been reached with the full power 1080, the 2080 uplift didn't bring enough performance increase value for dollar in laptops.

    The 2080 desktop has much higher performance than the 1080 desktop, but in laptops not a whole lot of improvement is to be found going from a full power 1080 to a full power 2080 what with vendors power limiting the GPU's in most models.

    Even worse was the performance decrease of the laptop RTX mobile GPU's against the desktop RTX GPU's for ray-tracing - with Nvidia throttling RTX performance (putting fewer tensor / RT cores) in the laptop RTX mobile GPU's. I'd watch for that to continue with the Super's laptop mobile GPU's

    See => Ray tracing performance of RTX laptops sucks
    https://www.pcworld.com/article/3336450/why-you-should-or-shouldnt-buy-a-geforce-rtx-laptop.html

    And, that's from the PCWorld review of the GS75 with 2080 Max-Q

    At that point they didn't know there was a reduction in Tensor/RT cores in the laptop mobile GPU's. There is a chart somewhere that shows the RTX throughput reduction in desktop vs laptop mobile RTX GPU's, I'll see if I can dig it up:

    So the next Full Nerd show #83 had more details on why Ray-tracing sucks on the laptop mobile RTX GPU's, and PCWorld provided a chart with the performance metrics from Nvidia including RTX Ops High / Low for Desktop / Mobile, and the 2080 desktop was 60/60 with the 2080 RTXmobile GPU at 37/53 RTX Ops:

    So I don't see how putting even higher power / cooling requirement GPU's - the Supers - will do anything except extract more $ from unwary customers.

    I'd be surprised if there weren't Super GPU's down the road, but be aware that the difference in performance may be simply a matter of raising the power limit and "briefly" getting higher numbers in benchmarks before heat soaking the cooling system.

    There was a much greater chance of higher performance from the 1080 to 2080 uplift than a 2080 to 2080S uplift.

    Again, we need to wait for production hardware to be in the hands of actual owners and trustworthy reviewers before we will know if the higher prices are matched with higher performance - but I doubt it's going to amount to any noticeable improvement in games.

    Mobile doesn’t have less Tensor and RT cores, the lower RT OPs is a product of lower clocks in Max-Q cards. Full fat laptop RTX cards would only have marginally lower RTX OPs as clockspeeds are close to desktop.

    That video is really misleading. Max-Q needs to be distinguished from the 150W+ versions, not just called “mobile”.

    If Nvidia released Super cards for Mobile it would be 880m up again.

    laptop has limited cooling so I would guess the super cards will skip laptops. We will have to wait until 7nm comes to laptops for any better graphics cards. They should be here soon from Nvidia.

    7nm for desktops next year. Then start binning chips for laptops. They won’t come before long time. In the meantime we will get “Super” cards from Turing silicon(Nvidia has already started bin Turing chips for next years laptops). Once again will notebooks experience Nvidia’s sick idea rebrand old chips as they did with 880M. Don’t expect 7nm graphics chips for laptops before Christmas... Next year. Or early spring 2021.

    My prediction is that 7nm will further lower the bar for mobile performance. The turdbook manufacturers will make them thinner and lighter to accommodate the hotter-running 7nm chips that lack adequate surface area to achieve an acceptable level of thermal dissipation, then throttle the snot out of them in a lame effort to offset their engineering idiocy. The glory days of high performance laptops ended in like 2012, save for a couple of freakishly awesome Clevo models that the kiddos love to hate.
