Manufacturers have had some time to stock store shelves and warehouses with Nvidia RTX laptops, but as Techspot pointed out earlier this year, the nomenclature can be very confusing. The laptop "RTX 2080," for example, doesn't have the same performance as the desktop version of RTX 2080, and there are multiple version of the "RTX 2080 Max-Q" with different levels of performance. Hardware Unboxed just tested the performance difference between the various versions. Check out their video here. 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.
