This might be a good way to go for extra docked performance.
Like I know power consumption would probably double or more, if you ran ~1800mhz on cpu + ~920mhz on gpu.
But honest who cares? The Switch is only useing like 20watts or so, docked... it going over 40watts wouldnt be a huge issue (as long as cooling allows for it).
Maybe make a docked only switch version?
With how little cooling is needed, you could easily make a switch with the same chip, that had those speeds.
(allowing for better docked performance/graphics)
