Differences are listed on this page:So whats the difference between a X570 and B550?
From what I saw it seemed that basically X570 supported PCIE4.0 But I have seen some B550's that support it as well.

In addition to what Ascend mentioned earlier, support for Ryzen 2000 CPUs might also be helpful for some.
I sold my friend my old Gigabyte Aorus X570 Master motherboard (after I upgraded to the Aorus X570 Xtreme) and he has been using it with the 2700X that he was using with his old system, until he upgrades to a 5000 series CPU.
I've read that some B550 boards do work on the 2000 series, but it is not officially listed as supported on the AMD B550 site.
