GraphQL out of the box doesn't make things optimized, but with any decent setup like Postgraphile, Hasura, or just DataLoader you do get highly optimized single-pass queries vs something like having many REST endpoints where the queries end up coming in piecemeal. I know this as I've been deep into these problems and it makes a huge difference in performance.
And the comparison is valid because these optimizations do happen and do make a difference, and are pretty easy to get if you just for example choose Hasura which is a very popular library (and there are many many others too). GraphQL makes this possible in the first place, whereas RSC and REST basically don't.
