Per chip is a bit misleading - the technology started running into barriers, so they just added more cores and increased die sizes. On top of that, clock speeds stopped going up, because one of those barriers is that energy dissipation from non-reversible switching became insurmountable all on it’s own.
Not everything can be done in parallel across cores, and software hasn’t really kept up with what can be done, so yeah old computers still work fine if you don’t add bloat. Meanwhile, good luck running Windows Vista on a computer from the mid-90’s.
