Much of that though isn't the hardware but a combination of devs having no motivation to optimise it for the AppleTV and the overheads of the OS. The Apple 4 HD (Obviously the lowest specced of all the 4th gen Apple TV's) for example has spec that's better than the Switch 1 and that was able to do 60fps on many titles. Some titles were awfully optimised and couldn't maintain 60fps consistently, and many intentionally capped it at 30fps when not docked for power reasons but even some titles on the Switch 2 that are badly optimised struggle to maintain 60fps. And lets be honest her the games available for the Apple TV are nowhere near as demanding as the ones even on the original Switch let alone the Switch 2
So more power alone won't automatically result in a better frame rate. It needs a much more efficient OS for starters which obviously for a 'do everything' box is much harder than it is for a console, maybe a game mode that shuts down every process not needed for gaming or even switching to game mode logs you out of tvOS and switches to a second streamlined gaming OS. Even then though it needs to sell more boxes so devs have a reason to optimise their games as right now all they are motivated to do is the absolute minimum.
That has always been the issue with Apple when it comes to AppleTV. They produce a box that for the main use case is too powerful and hence too expensive based and then kneecap the very reason for overspec by not optimising the OS to help it run games and by stifling the user base of the device. What they need to do is
- Increase the user base. They need the device (or a version of the device that's still fast enough to run games) to be sub 100
- Need to buy a medium to large game studio with a desirable franchise (or multiple) that they can make them Apple exclusives
- Find a way to make the OS more efficient when running games
Although TBH at this point their best bet would be to do a deal with Amazon, Nvidia or Microsoft to bundle one of their game streaming services into Arcade. With all the processing done remotely they don't need devs to port and optimise their games for the AppleTV, they don't need make the OS more optimised for gaming and they have access to big games and offer it for less than going to the service directly making the AppleTV a perfect device as a game streaming device at a fraction of the cost of buying a Switch, Xbox, Playstation or PC Handheld like the Steamdeck and while pricing it at around the same as a cheap mini-pc
