How do I know if the laptop I want to buy has a Max-Q or a Max-P?The short answer is: You can’t unless you have the laptop with you or check it out on a store. Following the recent changes by Nvidia with the 30-series GPUs, one thing is clear: OEMs are no longer obliged to use the term Max-Q on their laptop specifications.
It doesn’t matter how much Nvidia claims that they are encouraging OEMs to mention on their spec sheets the exact number of Cuda Cores and TGP for the GPU, this does not seem to happen anytime soon.
This also means that not mentioning the term Max-Q or at least the exact TGP on the specification sheet of a laptop may mislead buyers. Say for example, that you bought an RTX 3080 laptop with a TGP of 80W only to see that the actual performance of the graphics in games is quite similar to that of the RTX 3070 with a 125W TGP.
