This comparison is correct, but what I think
PaintTinJr
was getting at is 1 teraflop of Series X ≠ 1 teraflop of PS5. Yes they are both based on RDNA 2 ( which is more performant per TF compared 1:1 with GCN)
To pull another of Cerny's quotes from that presentation:
“If the ideas are sufficiently specific to what we are trying to accomplish, like the GPU cache scrubbers I was talking about, then they end up being just for us. “
-Mark Cerny
Now what does this translate to in the real world? This obviously doesn't effect the TF calculation, but does however increase the performance and efficiency of the GPU as a whole. Meaning that a PS5 TF will be more performant than a standard RDNA 2 TF.
How much more remains to be seen but this is an architectural change from base RDNA 2 that XsX does not have.
