Was browsing AMD website and found that they listed a new motherboard chipset (or a variant), called A620A
The last time this happened was with B550 and B550A
In that case B550A came first, and it was a rebadged X470, with B550 coming later and using a different chip, but offering slightly less lanes than B550A
Some leakers on twitter say that there is a variant of B550 chipset on AM5 under a different name, and it seems like it is actually A620A, as their specs pretty much line up.
So, Currently A620 uses a binned version of B650 chip, and to cut costs, A620A seems to be a binned version of B550.
This is clearly just a way to reuse older AM4 chipsets on new AM5 motherboards, as they're not that different in spec.

info from amd.com | USB 5Gb/s | USB 10Gb/s | USB 20GB/s | PCIe lanes | SATA lanes | Chipset uplink |
B550 | 2 | 2 | 0 | PCIe 3.0, 10 lanes | up to 6 | PCIe 3.0 x4 |
A620A | 2 | 2 | 0 | PCIe 3.0, 8 lanes | up to 4 | unknown |
