You probably aren't wrong, but when we're talking about enthusiast class products I'm not really sure things like "efficiency" or "power requirements" really matter all that much. At that level the only thing that really matters is raw performance (and maybe price). If Big Navi if performance competitive with enthusiast class cards then it being less efficient isn't going to matter.
I'd say that the degree varies. Big TDPs aren't a huge issue until they come with big noise levels, or when the GPU is extremely difficult to cool and has a hard time hitting performance numbers due to heat. Or power draw issues as we've seen from a number of AMD GPUs (and the 2080 Ti) in recent memory, where power draw overstresses aging or substandard PSUs.
And the bigger deal is that it's in comparison with what we already have. My overall point is that AMD's current GPU is both slower and less efficient than a competing part that has RT circuitry, which Navi lacks. Just scaling up the same architecture to Big Navi would infer the same relationship and then AMD is adding RT.
I have no doubt that AMD can build a competitively performing part; my doubt lies in whether said part will actually be competitive overall, or if they'll have to bargain-price it out of the gate to get any market traction outside of those that buy AMD because it's AMD or it isn't Intel / Nvidia.
