Has anyone even considered mundane stuff like power consumption (and its knock-on effects)? I mean a quick look at node and efficiency gains with the tech and honestly it doesn't look good especially as launch PS5 was already pushing 230W and even the latest (N6?) revision is still hitting ~200W and N5 vs N7 is only delivering ~ half the gains of 28nm vs 16nm not to mention AMD's apparently poor efficiency gains of RDNA 3/4 I've read here.
I think I've been disappointed with consoles for too long....
Goes back to shaking fist at cloud.
Thats why ps5pr0 can launch soonest holidays 2024, maybe even in 2025, all depends on when 3nm tmsc node will be avaiable, 7nm ps5 did reach 206W powerdraw even running crossgen miles morales, as measured by DF in their ps5 review.
U want 3nm ps5 chip to not go over 250, ideally dont go over 220W so gpu alone should be around 180-200W powerdraw.
For comparision this card
https://www.techpowerup.com/gpu-specs/radeon-rx-7900-xt.c3912 priced currently at
https://www.amazon.com/dp/B0BMWHCGBZ/?tag=neogaf0e-20 is easily 2x base ps5 gpu in performance but being made on 5nm node still has 300W tdp, ofc if u downvolt/downclock it heavily powerconsumption will go down significantly(to 200-220W) but performance will drop a lot too(maybe by 20-30%) so what we need is to see amd's rdna4 flagship gpu on 3nm, and then see how much performance it has at what powerdraw, from that we can extrapolate what could be in ps5pr0, gpu wise but 2x ps5gpu at similar powerdraw is very probable.
Ofc gpu in ps5pr0 wont be flagship chip hence i am comparing it to 5nm 7900xt so cutdown version which is visibly cheaper/can be produced easier too.
Full speculation mode, but lets assume 2nd half of 2024 amd debuts flagship card that is genuinely 3x stronger from ps5(very in the realm of possibilities since even current flagship card, 900$ rx 7900xtx made on 5nm tsmc node, is 2,24x stronger from rx 6700xt which in turn is stronger from ps5/xsx gpu in every aspect).
Then u can work with that, cutdown chip with much better yields would be around 2,5x stronger from ps5 base gpu, then u underclock/undervolt it and voila- u got 2x stronger chip from ps5 gpu that draws roughly same amount of power.
