Assuming the theory of performance somehow being improved or changed when docked is true...
How are we thinking the system will know if it is docked or not ? Will the system have a trigger that knows the portable is outputting to HDMI therefore it increases performance and cooling? What happens when the system is not docked but charging through USB C (rumored connection type) on the go?
In the NX promotional video you see the user at the airport charging while playing.Will the system increase performance on the go while it is plugged to the wall as well (I would think that it would not)?
Just curious.
The rumors are telling the dock isn't providing any more power but charging and HDMI output.
USB-C is a pretty smart standard from what I've read, so I think Switch will be able to know if you're on the actual dock, or just charging by USB-C. It's a safe bet, the fact the dock handle HDMI output can provide an alternate solution anyway (if not USB-C, the dock can have the necessary chip on board).
Secondly, IMO the docked/charging mode will just be here to remove underclocking and other battery saving features on the go.
*Switching* to 1080p and outputing to HDMI should be considered as an independent feature, even if it isn't technically possible to output thought HDMI without charging.
False edit: Actually the Switch HAVE TO know if the dock is a real dock or just an USB-C cable for charging. There's so much things who can't work properly otherwise.
Ex: Dock the console, you can't use the screen anymore so it has to switch to HDMI output nevertheless. If you're pluging a simple USB-C cable, this can't work, unless no matter what, the screen is still outputing your game. What happens to resolution then? Downscaling?
I leave it to you here; Too long already anyway
