Thats what im saying, first lets wait for amd gpu thats actually good enough to do 1080p native 60fps path tracing, then we can talk about it being downvolted/downclocked to reach console form factor(ps5pr0 had hard limit of 240W tdp from the wall, measured and showed in df vid, so lets not lie to ourselfs that ps6 gonna have 300-400W tdp limit, it will be at most 250, maybe 260W if pushed to the very limit).
Lets do this properly, guys, first tech has to be achievable from the very source, aka amd, their topend gpu, even with 350-400W, once it can do the task we can speculate about console downgraded version.
Lets remember ps5pr0 that launched barely 7 months ago is only up to 40% stronger in gpu power over base ps5 from holidays 2020(and thats official info sony/cerny bragged about in ps5pr0 trailer), its extremly slow progress techwise, compared to for example ps1>ps2 jump that took not even 6 years with around 100x performance.
Hell when going from ps4 to ps4pr0 we got over 2x so +100% gpu performance and that was relatively recently still, holidays 2013 to holidays 2016 after all...
