It is a console, these are not directly comparable. I would rather compare to premium console experience of last gen.
PS4 pro has about 3 times more computing power than PS4, launched at the same launch price as the og PS4 3 year latter.
PS5 pro is 200$(~300$ or more depending on the region) more expensive than PS5 launch, and it is not a complete product (lacking vertical stand and disk drive).
