I don’t see any dramatic differences, but it might have a performance edge in some games over the Xbox Series X.

So, for example, right now it looks like Star Wars: Outlaws runs better on the XSX vs. PS5.

Pro version? Unknown. Should be better.

Just like last gen:

Xbox One < PS4 < Xbox One S < PS4 Pro < Xbox One X

Xbox One Series S < PS5 < Xbox One Series X < PS5 Pro(?)
