To literally shrink the PS4 chip to the point where it could run in a Switch sized device without burning/melting itself after 2 hours of play is still several years away. Those chips were never designed to be in a mobile device.
Nvidia will have Tegra X3/Xavier for Nintendo ready well before then.
Sony is not gonna win on tech, there is nothing special Sony can get that Nvidia won't be able to match/best.
The difference too is IMO under Kimishima Nintendo is not going to just roll over and allow Sony to step onto their turf this time.
Nintendo is willing to put *new* installments of their top IP ... is Sony willing to do the same and make the PS5 wait for the next Uncharted? Don't think so.
