RTX 3090 in a gaming notebook?

I would have the following question:

Why are there gaming notebooks with the RTX 3080 (Asus rog SCAR 17 e.g.)

BUT why are there none with the RTX 3090?

Thank you

Too big, too heavy on batteries, there are many reasons why not

Yes, but there's not much difference between the RTX 3080 and the 3090

with battery and co.

So the size of the PCB is the same for 3080 and 3090, but the temperature will be a big problem. The 3090 has VRAM modules on the PCB (because of 24GB VRAM) on the front and back, which get really hot, so you can hardly keep up with normal air cooling, in the laptop the card would probably be throttled by too high temperatures.

You will probably get it at some point, but thank you lg

I think it would be possible, but as far as I know there were no / hardly any laptops with a Titan GPU and the 3090 seems to be this generation of the Titan GPU of the 3000 series…
