Slightly ahead of its launch, ASUS flashed a banner of its AMD B550 chipset motherboard lineup, revealing two other boards than the premium ROG Strix B550-E Gaming AMD unveiled in its platform unveil. These include an unnamed micro-ATX board slotted in the TUF Gaming series, and a entry-level Prime B550M-A micro-ATX board. The Prime board has our attention as its spartan layout could indicate that there will indeed be socket AM4 boards based on the B550 starting at $100, as AMD promised. The B550 has a distinct advantage over the B450 in the form of PCI-Express gen 4.0 for the main PEG and at least one M.2 NVMe slots; and an easier upgrade path toward 4th gen Ryzen "Vermeer" and "Renoir," than AMD's 400-series chipsets have.
