Can either of you name one affordable mobile device from 2017 that was capable of playing console-level games for more than two hours without thermal throttling like crazy besides the Switch?
The answer is no. For it's time it was a genuinely solid piece of hardware. Saying "ERM ACKTUALLY ITS A 2015 NVIDIA CHIP" is irrelevant and evidence you don't really understand what you're talking about. You do realize most consoles and mobile handhelds tend to use off-the-shelf components as a base that are already dated upon release, right? The original Xbox was a complete powerhouse for a console at launch and yet it was a generation behind the Pentium 4 on the PC side.
Even then, the Nvidia Tegra was incredibly powerful and efficient compared to other ARM solutions, so it being a few years in at that point didn't really matter.
I think the Switch is incredibly dated and long in the tooth at this point, but you can't really argue that Nintendo did the best they could do for an affordable handheld console. Newer Nvidia chips would've been far too costly and most likely not as efficient for what Nintendo was trying to achieve. Asking 1080p out of even 2017 mobile hardware was far too demanding. Even a 2022 Steam Deck x86-64 APU can't really achieve this well, and it's far more powerful.
