When will Watercooling come to Laptops and is it possible?

The new 3080 mobile gpu sucks compared to the desktop 3080 version. It’s because of the low TDP on the mobile version that crippled its performance.

Anyways, the only way I see anything close to getting that desktop performance shoved into next generation laptops is if they incorporate water cooling, and up the TDP on the mobile 3080 chips.

What do you guys think?

asus, i think, has done it before with a hybrid docking station thing. space isnt there in most models.

Wow, got any links to that Asus laptop? Didn’t know they SLI’d 1080s on laptops.

I know space should be a concern, but I don’t think it has to be.

P.S found the Asus laptop on Amazon, thanks.

I think they could implement watercooling with thinner blocks a bite size reservoir & ultra thin radiator although air flow is tricky plus the thickness of the laptop would be huge. Speaking of huge I don't see why they don't have much thicker air cooler versions with huge copper heatsinks with an extremely vented bottom & sides with slim 200mm fans pushing cold air up & out the sides. It would be an engineering challenge but can't be that hard? Of course it would be at least twice as thick maybe thrice as thick but it would perform great. Another challenge would be because of the thickness your where you lay your forearms in conjunction to where your fingers lay on the keyboard would be way higher and off although could be remedied by a creating a platform for your hands or wireless/detachable keyboard although defeating the purpose of the laptop but making it a portable kit haha basically It's a big challenge lol

Nothing is "that hard" if you're just making one-offs, but good luck getting something like that ready for mass production without an exhorbitant price tag. Also, a slim 200mm fan sounds like a terrible idea. Frail, low pressure, and would take up a bunch of space that would be better served by multiple smaller fans.

Liquid only cools better than heat pipes when you're able to use a larger and/or better-placed radiator and more fans as a result. In a laptop, the liquid cooling setup would take up more space, which would be counterproductive.

Or how about just having more efficient gpu’s? Battery power also matters to folks on laptops, even gaming laptops. Trying to engineer water cooling in a laptop is really the wrong way to solve a problem likely from a financial standpoint. We need better gpu efficiency.

We already have that as well, if you bare willing to compromise on peak performance; the 3050 Ti adds 25% higher battery life over the 3060 (as the voltage curves and peak tdp are lower)

You can only improve the performance / watt of an architecture so much!

Nailed it. A watercooling setup in the space of a laptop will be less efficient than the standard heatpipe setup. Watercooling's slight advantage in this scenario is that it will be a little bit slower in heating up, but will reach a higher equilibrium temperature.

That's why you're supposed to choose the balance of specifications that make the most sense to you. More efficient GPUs will come around with new architectures, which is the natural progression of things. I think it's a good thing that we have the option to get powerful but less efficient GPUs in laptops for those that prefer that setup.

That's at stock settings. I'm almost positive that you would get more efficiency by under-volting and under-clocking a 3060 vs a 3050ti at the same performance level. "Slow and Wide." I haven't kept up with the new stuff, but that's still possible to do, right?

Yea a egpu is probably the correct approach. But actually water cool a portable laptop seems like a terrible idea.
