what are the different workloads for driven execution vs fixed rate execution of a query tag?

for example 12 hours fixed rate vs a tag that updates every 12 hours

That is exactly the same thing.

A fixed rate tag is a tag you want to **poll** at a certain interval. Driven execution is where the query only runs when it has to, IE a query parameter has changed which triggers the query to run.

I mean more internally.

Or said another way, that because they are same to me, as you pointed out, is there a difference internally worth considering?

I don't think so, no.
