Speaking of bizzare math calculations, what you're saying is quite bizzare. The ps5 pro is infinitely better? That's certainly a take....
Anyway, Cerny himself claims "
up to 45% better" here:
Many have benchmarked it and found the Ps5 Pro to be on average ~30-35% faster. There are like maybe 5 games where the pro makes a noticeable difference and in most of those cases, it's because of the use of a bad taa implementation from the developer.
So off the top of my head, space marine, FF rebirth, ac shadows, are games where even the average joe can see the differences. However, these games are the exception not the norm. A lot of ps5 pro games are just middling. Again, I purchased 2 ps5 pros so I'm talking from experience.
Again in cpu limited scenarios, the pro offers a similar boost to the ps4 pro and a worse boost than the xbox one x. See here:
