I've got an old MacBook Pro from 2013 that I still keep around because the keyboard is the best Apple ever made. It's not fast by any means, but I haven't encountered any difficulty with websites whatsoever. They're not as snappy as I'd expect on new hardware, but perfectly usable. I do use uBlock Origin, however.
Are these Androids actually less powerful than an 11 year-old, base-spec MacBook?
