Fairly self-explanatory but I can't find any detail on this. Alienware, as an example, sells the Aurora R10 which is a B550a board. Gamers Nexus did a breakdown and from what they've said it looks like a B450 + PCIe 4.0 support.
If this actually the case, or is it more of a B550 offshoot or a B450 offshoot? If the former will it B550a be given access to the Zen4 agesa updates? If it's the latter, will it be left without the Zen3 upgrade path despite its B550 moniker?
Thanks in advance if anyone can answer this.
