If only your CPU becomes a limiting factor at one point you can simply upgrade your CPU to a few generations newer cpu without having to swap out your motherboard. You can’t really do that with Intel (AFAIK they switch platforms every 2 CPU generations so depending on your CPU you may not be table to upgrade at all (can happen with AMD too, but not that frequent)
Intel until they realized that other companies made CPUs, too
They also bring a “dying transitor problem we don’t feel like fixing” to the party, too
And a constantly changing socket so you have to get a new motherboard every time.
Honestly, not a big deal if you build PC’s to last 6-7 years, since you will be targeting a new RAM generation every time.
Upgraded from a 1600 to a 5600, same mobo

With no multi threading
I mean the i7s had SMT. You had to pay extra for SMT, whereas AMD started giving it to you on every SKU except a few low-end ones.
