I don't know why you've stated the obvious.
Sometimes you must realise you haven't understood the point, rather than someone making a mistake

Steam in Home Streaming (Which frankly is where these devices would shine, rather than native gaming, so you may's well go ARM and just rely on it)
Steam Link is an ARM powered device, yet I've no problems using it to play Witcher 3 on the 55" downstairs etc.
In a similar vein to me playing "The Last Of Us" from my PS4 to my Sony Android phone (Which after updating my network to a rather hefty albeit not top of the line AC router was running flawless)
As long as your network's robust, there's not a vast deal of limitations. I've got an Asus Ultrabook (Fanless, low power CPU) 3200x1800 screen. I can use CRU to render Witcher 3 at 3200x1800 for example and then stream it to my Ultrabook. The image quality maxed out at the 100mb limit though.
