oh damn gotcha. It made sense in my head that there was no fucking way those absolute heating units in the 30 and 40 series could ever be put in a laptop without melting it so that makes sense.Some are, some are not. It depends on the generation of GPU. Currently, all of the announced 40 series laptop GPUs are actually equivalent to one tier lower desktop GPUs, so that a laptop 4090 is actually a desktop 4080 chip and so on. On top of that, the laptop GPU has a power limit which much lower than the desktop one.
It used to be that laptop models would be called MaxQ or simply XXXXm to reflect that, now not anymore.
The gap gets bigger the higer end the GPU is: a 150W desktop GPU and its 90W laptop version are not going to be as far apart as a 450W desktop GPU and its 175W laptop one.
Then, even when you have a high end GPU in a laptop, it could still be a low power version of it. You really have to read the laptop's specs sheet carefully. A good hint is the power brick, if it's a <150W power brick, it's most likely not a full power mobile GPU. A laptop 4080 at 150W is not the same as one at 90W, thickness also changes a lot, although the manufacturer will happily charge the same.
As for the 1650 though, it's one of those GPUs that had almost parity between desktop and mobile. Laptop and desktop GTX 10/16 series were much less apart than RTX GPUs are.
And yea, I also thought they were labeled MaxQ or Mobile or whatever. I didn't know they just made that go away...that's fucking scummy if you ask me, because the usual buyer will have no idea of the differences...though I think that's the point...
thanks
