Here is the first picture of a motherboard based on AMD's upcoming mid-range desktop motherboard chipset, the AMD "B550A," the ASRock B550AM Gaming. The board was spied inside a pre-built desktop at a Best Buy store. This is the first time we've seen the mid-range chipset being referenced as "B550A" and not "B550." The "A" may not be part of the motherboard's model name as the "M" denotes Micro-ATX and usually succeeds the chipset model in ASRock's nomenclature. The B550(A) will be an important chipset for AMD as it will enable motherboards priced under the $150 mark that support AMD's 3rd generation Ryzen processor's I/O natively.
While the X570 is an in-house development by AMD, the B550 is sourced from ASMedia, and is expected to be a new version of the "Promontory-LP" silicon. The only thing that sets this chip apart from the 400-series "Promontory-LP" is PCI-Express gen 3.0 certification. The chipset talks to the AM4 SoC over a PCI-Express 3.0 x4 link, and puts out up to 8 PCI-Express gen 3.0 downstream lanes. A 3rd gen Ryzen processor on a B550 motherboard still puts out PCI-Express gen 4.0 connectivity, which means you get one PCI-Express 4.0 x16 slot, and one M.2 slot with PCI-Express 4.0 x4 wiring. The rest of the chipset's I/O will be similar to the 400-series, which includes six SATA 6 Gbps ports, up to two 10 Gbps USB 3.1 ports, up to four 5 Gbps USB 3.1 ports, and eight USB 2.0/1.1 ports. If the AM4 SoC installed is a 3rd gen Ryzen, then you'll get a couple more 10 Gbps USB 3.1 ports. AMD partners could use the opportunity to launch some of the more upscale B550 motherboards with the latest 2.5 GbE wired LAN, and 802.11ax Wi-Fi 6.
Update (16/10): We learn later down in the referenced Reddit thread, including from comments by AMD's Robert Hallock, that the B550A is a rebranded B450 targeted at OEMs. The B550 (non-A) is what is the upcoming chipset detailed in this article.
