I see your point, but i feel like the Video might have been a bit biased, because CPU does often matter a lot. There are of course instances where series s runs at below 1080p but it usually runs at 60 fps or at least stable 30. An example of CPU differences is Star Wars Jedi Fallen Order. It has a 1080p Performance mode on series s and on one x and on series s it's locked 60, while it is 35-50 on one x.
