Full path tracing at a decent performance (40fps) is a pipe dream on ps5 pro, right?
Lets check how good cp2077 runs with it, aka overdrive rt settings
Thats ofc on currently strongest gpu aka 1600$ msrp rtx 4090 that has 450W tdp on its own
https://www.techpowerup.com/gpu-specs/geforce-rtx-4090.c3889
As u can see in the vid, dips under 20fps in 4k native.
How strong ps5pr0 can get in comparision to rtx 4090, assuming its gonna be rdna4 archi from amd, on 3nm process(so earliest launchdate holiday 2024)?
We wont know for sure till we see amd's flagship card and how it performs ofc.
Logical estimates giving power constrains(max 250 W real power draw for whole console) would point towards 2x raster(so non rt) performance, in layman terms games that run in 4k30fps on base ps5 would have enough headroom to run in 4k60 at same settings.
RT performance depends on how big gainz amd gonna make in their new rdna4 cards, obviously gonna be big, maybe even close to current 4090 but who knows, maybe it will be 1 tier below?
Another comparision, just for fun ofc, but with current amd tech avaiable for us right now, i would expect max ps5pr0 can be now is downclocked hard gpu same or tiny bit cut down rx 7900xt (it has 300W tdp so downclocking it hard and cutting a bit would have to be done), its price is around 750$ atm so relatively low

Bear in mind thats made on 6nm process so 3nm would help a ton with powerdraw(wouldnt help with more oomph, which not downclocked its about 2x ps5 base now, so downclocked would probably be around 1,6-1,7x only).
Thats the reason we need that lil bit more push/time so die like that on rx 7900xt(529 square mm) can be bit more powerful and if made on 3nm node will be vastly more powerefficient, on top of increased rt performance coz of rdna3 to rdna4 jump.
