This would be a bit technical, but I'll try to simplify it as much as possible.
A processor of any kind needs electric (duh) in which case the motherboard is receiving from the power supply as voltage. But the processor cannot just use that voltage as is, it needs to be be phased out till the point where it is low enough and not too high for it to work, as specified by the processor design. Too low of a voltage causes instability, too high of a voltage causes monumental heat increase. There has to be a correct balance.
So VRM phases will take the voltage and filter them out, as many times as the phases are available before going through to the processor. Generally speaking, the more phases there are, the more times the incoming voltage will be checked and thus the more accurate and clean the current will be. So if there are 6 phases, the voltage will be checked six times.
But of course phases aren't free, the more phases there are, the more difficult it is to implement. It's not simply just getting more mosfets and slapping them onto the board.
To go back to the PS5, I'm not making any conclusion until there are high res pictures of the motherboard. I do not know what mosfets they are using and the caps look to be sufficient too. But Cerny mentioned how they are controlling clock speeds in relation to temperatures, but in order to have a correct balance on that - the VRM section needs to be robust too. From the teardown, it looks good enough but again, no conclusion because it's not close enough to see what components they are using.
so basically now the thing depends on the quality of components..
again I believe the price of PS5 should've been a bit lower compared to XSX as its even falls a bit short in terms of raw power too...
