The way I see it is the low power mode is the back compat mode and isn't ideal but will get the job done. The device will primarily be a PS6 handheld because it will have access to all the generational features that enable scaling in a more elegant fashion. PSSR2, texture compression etc. They will be able to scale off 640P (or lower) vs 1080/1440P for the PS6. The key will lie in not skimping on memory.
I also think people are underestimating how much the ML hardware will be leveraged in the next generation vs this one. People get tunnel vision over upscaling without appreciating that is the tip of the iceberg. They have talked about GPU compression as a bandwidth multiplier, but there are specific ML patents around texture reconstruction that in essence take full fat textures out of the game install and instead abstract them into something analogous to a vector descriptor for ML reconstruction in real time.
Its this type of generational refactoring that is going to allow something like a PS6 handheld to perform better than what we are currently seeing in handhelds. They lack the efficiency multipliers. Mind you the tech isn't going to be adopted widely immediately, so the handheld might actually not show its true potential for a few years! Well unless 1st party titles showcase the potential deliberately.
If people doubt I just point to Mark Cerny saying even they don't know all the ways the hardware will be leveraged yet by devs. (something along those lines anyway).

Re: In Theory: Could Sony's next-gen handheld run PS4, PS5 and even PS6 games?
