What Is The Difference In Amount Of Vacuum Tubes To Amplifying Circuits Used To Make Computers?

I’m doing a report on the History of computers, and I can’t find this answer straight forward. I know computers switched from Vacuum tubes to amplifying circuits, and some computers used like 18,000 vacuum tubes- In contrast with the amplifying circuits, does each computer just need one? or a couple? I mean was it all those thousand tubes to the one circuit that made it such an improvement? Or did it just need …less.. Like 100 circuits or something?
