Where can I see a comparison of processor performance when working with browsers?

Question

Software testing

My main working tool is a browser, 100,500 tabs are constantly open in it, 1050 extensions are installed, so when choosing a new processor, I would like to be able to compare how fast browsers can work on a particular processor. The same question, in principle, applies to other iron. Have you seen the results of such tests?
UPD I found one test, but there the search by results is probably only suitable for choosing a phone:
