Just going to have to take it for what it is. An Arm processor tied to a mobile SOC isn't going to offer sustained performance of a modern X86 CPU. Especially not Zen 2 with eight cores with MT.
There's also the issue of storage space, speed and I/O which is going to another factor in the equation. I can't imagine Nintendo investing in even more expensive NAND cartridges for games. That's gonna get expensive, fast. Nintendo likes making money off hardware.
Then there's publishers hurdle. I can't see a modern GTA released on a Nintendo console anytime soon. I mean how is it that GTA V is on every console including a toaster but not on Switch,
