I think it's good, but I haven't seen any miracles here compared to what dedicated hardware can do.About bandwidth worth reminding that Sony said the bandwidth available would be comparably more efficient on PS5 Pro, somehow.
On top of better GPU cache architecture (doubled L0 and L1) that could help explain that claim I think memory clock (2.25ghz) been very close to GPU clocks (? 2.18-2.35ghz ?) could also help. On PS5 the difference of clocks (1.75ghz vs 2.23ghz) was not helping bandwidth efficiency according to Cerny.
I think as we've learned more about PSSR, the real comparison point is XeSS DP4A vs PSSR. that is probably the closest we can get to comparing 2 to upscaling networks, running on something like a 6700.
