What is the computational complexitycost of gradient decentdescent vs linear regression?

I know the computational complexitiescosts for the closed form of linear regression is O(n^3)$O(n^3)$, but I can't find a similar complexitycost comparison to gradient descent.

There are some similar questions here with people "talk" about how gradient decentdescent is more efficient and present some formulas that are not in the form of O(.)$O(\cdot)$ and do not include where they got their information.

So to reiterate, I am looking for the computational complexity for gradient decentdescent in the form of O(.)$O(\cdot)$, something where O(.) < O(n^3)$O(\cdot) < O(n^3)$.

It's possible I'm thinking about this wrong and there is no big O$O$ comparison. If so please let me know. Thank you.
