Every time I look at this thread, it is amazing how little people know of mobile hardware. AMD announced the CPU cores for the PS5 (FIVE, NOT FOUR) in a mobile chip, running at 1.8ghz, and it only uses 15 watts. The Ryzen 4800U. Even I was surprised.

That is what is possible in 2020 with a mobile CPU. And people wonder if the next Switch can equal the PS4? We can already put the PS5 CPU in a Switch (but not the GPU of course). It is up to Nintendo, and how much they want to charge for their next system. That's why I think Nintendo should make a $399 mobile system and really show what is possible in 2020 with mobile hardware.
The PS4 is nothing special in 2020. Even in 2019 we have the mobile version of the GTX 1650 from laptops running at half clock speed like the Switch (1ghz): it uses 20 watts on average and beats the PS4. Shrink that to 7nm and it is a piece of cake to beat the PS4 if Nintendo wants to do so. CPU and GPU.
The Snapdragon 865 will most likely beat the PS4's GPU, and the CPU by 4x... Let's not get started with the next iPad PRO which will have a CPU that will absolutely smoke the Ryzen 4800U and the PS4. Geekbench 5 scores will be over 1400 per core (14x faster than the Switch most likely).
