probably a mini with an A12X?
Sounds reasonable. With capable performance for all the relatively low demanding games in Apple Arcade – with some exceptions – some of which struggle on the A10 in the current Apple TV. I mean the game Monomals (for example) running at 30 FPS at a 1080p television isn't a very great experience.
I guess Apple will go their own path when it comes to gaming, letting games created for their mobile plattforms also run on the Mac. Seems they aren't trying to compete with the heavier games on consoles and Windows, at least not in the short term.
