You're conflating cooling solution with the decision to go for fixed vs. variable. The PS5 was designed with variable, continuous boost, constant power delivery from the outset which allows them to clock much higher. I wouldn't say one is better than the other, but PS5 is certainly more interesting.
I guess it's "interesting" in the sense that it's really only something that's been done with PCs in mind, but whether that being interesting actually translates to gains in performance beyond what we can currently imagine, we'll have to see. I just take Cerny's "better-than-linear-scaling" comment as PR fluff though, because RDNA1 cards don't scale performance very well at higher frequencies.
It's possible the problem's been resolved with RDNA2 though; RDNA1 resolved the frontend bottleneck FTMP and RDNA2 even moreso. It's very likely both PS5 and XSX will benefit greatly from advances by AMD on the frequency scaling-to-performance and frontend bottleneck removals for RDNA2.
Indeed, You should remember that Cerny said that The Tempest 3D Audio is an equivalent of 9x ZEN2 cores! And Kraken is as powerful as all 8x Jaguar cores inside PS4. I don't think they can open the devkits to check them from inside as stated by

, and the app/program used to estimate overall power won't take into account those unconventional customization. So this is my guess list for the inflated numbers:
9.2TF > 11.6TF
10.3 > 12.4TF
10.6-10.9 > 13-13.3TF
He was so angry because people are bashing him and all insiders in a very bad way. Let's give them a break.

what's your take?
My only question with them then is why did they not factor XSX TF performance figures in a similar way? It has a lot of the same customizations going by what MS has mentioned, even if the SSD is about 2.5x slower (well, the flash memory controller, anyway). IIRC one of XSX's chips for SSD purposes is equivalent to 5 Zen 2 cores, and it has the dedicated audio processor as well, etc.
If they were factoring in PS5's CPU, custom chips etc. to arrive at those PS5 numbers that didn't end up being reflective of just the GPU, and if they knew specs on both systems, why was that not done with XSX numbers as well? Maybe their sources were the ones responsible? It would've been more helpful if they just gave them the GPU numbers only because at that point everyone was only focusing on the GPUs.
