    Desktop 3080 will eat 320W. I was planning on buying the next iteration of Razer Blade Pro with RTX 3080, and those are usually capped at 90W. It’s not going to be anywhere near close to the desktop 3080. Power consumption for ampere is nuts, but it’s fitting for the architecture name.

    comparison: GTX 980 was a 180W card for desktops. Laptop 980M would eat 100-120W depending on the VBIOS and power delivery components (note, NOT THE MOBILE 980) and that was 20-40% away from the real desktop 980 performance. Nvidia should have just stuck with the M suffix for their GPUs because they will never ever be anywhere near their desktop counterparts.


    Who knows what the deal will be for Mobile 3080. The Area51M tried to deliver desktop 2080 performance and ended up blowing mosfets right and left. Dell clamped down and reduced the max power consumption of the cards and nerfed them. Keep in mind desktop 2080 power consumption was around 225-230W at the time. Ampere is not wildly more efficient than Turing. The just made a fat core and fed it more power

    The A51M had a poor design. There are so many others that handled the 200w 2080 well.

    I'm hoping this forces laptop makers to innovate and come up with really good designs.

    Can't wait to see Ampere in laptops, I hope we get 300W TDP for the max-p GPU. I think laptops can handle that kind of power. My laptop can handle 2x200W SLI GPU and keep it under 80ºC. I know is not the same but it can't be that far either

    I'm looking for medium sized ones handling 200-250w with a novel cooling systems. Like a huge vapour chamber with fins all over it and not just at the exhausts.

    What's a medium size laptop for you? 15 inch? I don't own a desktop PC (well I own one but just as a HTPC server) so I like desktop replacement kinda laptop where you could perfectly fit a 300W GPU

    2.7-3.2kg laptops like the GE75/Scar 17

    Not thin and light but not desktop replacement

    How is a 6-7lb laptop supposed to sink 300W without sounding like a wind tunnel?

    According to the laws of physics, it can’t. 300W will need a very beefy heat sink and fan setup

    With Intel going for 10nm and more power effiency chips we will only see thinner and lighter models. Not thicker or heavier with adquate cooling. The cooling setup will follow same paths. Downwards. From worse to even more worse. Apple here we come. And some here dreaming about 250-320W graphics in tomorrows notebooks Jokebooks, LOOL

    I did say this long back back, Intel 11th now has TB4 and Wifi 6 logic board soldered and also the RAM capped to 16GB LPDDR5 or slower DDR4.
    I doubt most OEM will be able to handle 200W of 3080 Super, let alone 3090 Max-P/Q/A based mobile chips. One way they can leverage is through soldered DRAM/VRAM crossing 12GB for caching huge texture and lower GPU clocking to sub 900MHz and push to 4k 60 easily with DLSS 2.x. So, a combination of super fast NVMe, big VRAM and more RAM can turnaround mobile laptop gaming in theory. Even if they manage that, there will be heat and you need separate fans and impressive passive cooling to cool off PCIe4 SSD, 3800MHz+ DRAM, 4.5GHz-4.9GHz all core CPU and GPU clocks and DRAM freq. Thin and light books have it tough now.
