So I looked a little but further, I searched "does android support external gpu's?"
Basically you would need a custom driver which doesn't exist yet? I think. I've heard of installing android on your computer though so not sure if Google already has a small driver somewhere for support of at least a few gpu's.
As a product, this could be very interesting. I love using splashtop on my phone and plugging it into my tv and using a mouse and keyboard to control it from the clutch, it's very useful and very portable but if Google were to make some sort of dock (like the Nintendo switch) you could plug in your phone,turn off the phone display to save power, and restart android with the installed external GPU next to your tv?
Does anybody who works at Google wants to pitch this idea?
