The Subor also doesn't have the same low level API the consoles have, which would lead to more power consumption to get the same results. Put a comparable 2TF PC up against a PS4 and not only is it going to struggle to try and match it, it's going to do so at a much higher price, while consuming more power. Navi will definitely improve on performance per watt, and probably more than you would expect if PS is directly involved, otherwise PS5 might as well just use Polaris or Vega.

Can't forget the Power Supply efficiency as well. If the Subor has an 70% efficient unit and the Xbox One has a 90% efficient unit, that can account for 20-30w of power right there as wasted.

Forget? LOL. Another good point though. While I can't find the PSU spec for the Subor, with Pro having a 4.2TF GPU spec with a 310w PSU, and XB1X having a 6.0TF GPU spec with a 245w PSU, it probably fits somewhere in that range of efficiency vs performance. It is important to point out that yes, that can make a pretty big efficiency difference with just one component like the PSU, since those two consoles use pretty similar hardware, with XB1X having more premium components and a clear performance advantage, yet a much smaller peak PSU output. While the Subor uses Ryzen, and Polaris with some Vega baked in, Zen 2, Navi, GDDR6, etc, if they ended up in next gen consoles, would be that much more efficient vs their gains in performance. Like you say, the marketing numbers only tell a fraction of the story.
