[DC] Was Superman always super smart? What's his traditional power set? What's Rebirth's?

I've read a couple different comics where Superman reads every book in a hospital 5 minutes before performing life saving surgery, or reading two different planet's history before deciding who to back in a conflict. Has he always been a god-tier speed reader?

In the Earth One graphic novel it shows that he is insanely smart and uses it to test out what he wants to do with his life before he lands on journalism. He solves a physics equation that a company has been working on for years and they offer him a job on the spot, and he's also seen trying out for work in finance, chemistry, art, architecture and sports too.

The speed reading is of course part of the power set he has but he's inherently intelligent, the House of El on Krypton was made up of the greatest scientific minds in the universe and his father Jor-El had often been described as the greatest.
