PSA: If you're buying a 1660Ti/2060 laptop now, take note that 2060 runs cooler despite same 80W TGP (I guess it's due to lower voltage and larger die size). Also it's faster (10-15%)

    And this is across most laptops? Interesting!

    From a few laptops I've seen so far, yes

    Cannot 100% confirm yet, but from what I heard from resellers (Illegear and Level51 aka AftershockPC), they've noticed the same thing

    I'd imagine it might vary slightly between laptops due to how they'd each choose to cool the GPU die, but assuming most of them use similar methods, it might come down to voltages, clocks and heat dissipation size as you said. 

     

    Havent followed Laptop GPU's recently, but are they still full fledged die's (full CUDA core count, ram, ETC) as the desktop versions? I remember the Maxwell and previous versions had M variants which were easy to distinguish as cut down versions.

    10 series have some cut down versions in laptop GPUs (eg 1050) but Nvidia didn't nerf too much clock speed. This has a side effect though: GPU sometimes run too hot due to high voltages (over 1V).

     

    16/20 series is worse IMO. Some GPUs are heavily power capped (eg 2060, 1650). In general, all of them have slightly lower clock speed compared to desktop counterparts. A step back if you ask me. Still have some GPUs with nerved specs though, for example 2060 has lower RTX-OPS in mobile version.

     

    Another issue is, Nvidia didn't specify a fixed TGP for some mobile GPUs, causing chaos when choosing laptops since same GPU might have different performance. For instance:

    1660Ti - 80W or 90W (Tongfang only)

    2060 - 80W , 90W (MSI models, Clevo NH50 with latest BIOS, Legion Y740 15 with Performance mode etc) or 115W (Tongfang only)

    2070MQ - 80W, 90W (Predator Triton 500, Legion Y740 with Performance mode, RB15 etc) or 115W (Tongfang only)

    2080MQ - 80W, 90W (Asus Zephyrus), 100W (RBP17) or up to 150W (Tongfang only)

    2080: 150W to 200W
