The fact that Nvidia can cram a 545mm^2 GPU into a low-power laptop at all is remarkable, and generally speaking, the RTX chips perform well in their relatively small power envelopes. But as the video points out, be careful if you're in the market for a gaming laptop, as the actual performance level of some RTX GPUs can be difficult to discern. Wonder how screwed must someone feel after upgrading from a GTX 1070 laptop to an RTX 2080 Max-Q one.
