Switch was on a very poor node, the TSMC 20nm, which had leaking issues. We documented it on the old old site, The Nvidia Shield TV would try to run the CPU at 1.9GHz and the GPU at 998MHz, but would throttle whenever both were in medium usage range, the CPU clock would drop to 1.4GHz and the GPU would drop to 921MHz, if both usage was at 100% the clocks would drop even more. Nintendo should have went with a 16nm node, but the chip was designed and manufactured at 20nm, we see with Mariko, just 2 years into the Switch's life, how drastic the power usage dropped.
Switch 2 isn't in this situation though, it's a custom chip, made specifically for Switch 2, and thus, it's size and power consumption will align with the design of the chip, there is no reason to make the chip as big as it is, if you clock it TOO low, because a smaller chip with higher clocks would perform the same and be cheaper. Switch 2's specs are known, and the clocks are obviously in a range where a cheaper chip couldn't do the same job. That is what we know, and with that knowledge, I can confidently say that even on minimum specs for the size of this chip to make sense, it will be far closer to the PS5 than the Switch was to the PS4.
