The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Others

For the launch of AMD’s B550 chipset, Biostar has a pair ready to go with an ATX sized model and micro-ATX sized option. Both under its Racing moniker with flashy looks and controller sets catering more towards entry-level models, and it’s possible we could see Biostar release the B550GTN mini-ITX mode at a later date, although Biostar hasn’t unveiled any details of this at present.
Starting with the larger and more premium of the pairing, the Biostar Racing B550GTA an ATX model which looks very intriguing on paper. The most contrasting features of this model include a Realtek 2.5 G Ethernet controller while opting for an old school Realtek ALC1150 HD audio codec. Also present are two M.2 slots, a pair of USB 3.2 G2 ports on the rear panel, and support for DDR4-4400 memory.
Focusing on the design, the Biostar Racing B550GTA has a black and light grey patterned PCB which resembles sun rays, similar to that on the Japan national flag. It includes a black power delivery heatsink which doubles up as a rear panel cover, while the chipset heatsink includes a Racing logo and has white contrasting lines. The board includes two full-length PCIe slots with the top slot operating at PCIe 4.0 x16 slot and the second slot locked to PCIe 3.0 x4. There are also three PCIe 3.0 x1 slots with a legacy PCI slot and is the only B550 model at present to feature this. For storage, Biostar is advertising two PCIe 4.0 x4 M.2 slots, but this is likely an error in the specifications and one slot will operate at PCIe 4.0 x4 and one at PCIe 3.0 x4. It also includes six SATA ports with support for RAID 0, 1, and 10 arrays. The B550GTA includes four memory slots with speeds of up to DDR4-4400, and up to a maximum capacity of 128 GB.
Over on the rear panel of the B550GTA is a pair of USB 3.2 G2 ports including a Type-A and Type-C, with four USB 3.2 G1 Type-A and two USB 2.0 ports. Biostar includes a pair of video outputs including an HDMI and DisplayPort output, a PS/2 keyboard and mouse combo port, as well as a Realtek RTL8125 2.5 GbE Ethernet port. Finishing off the rear panel is a Realtek ALC1150 HD audio controller which adds three 3.5 mm audio jacks.
The Biostar Racing B550GTA is a little bit of a mixed bag with some core features attributed to the B550 chipset including USB 3.2 G2 connectivity and official support for PCIe 4.0. The decision to combine a premium Realtek RTL8125 2.5 G Ethernet controller with an older ALC1150 HD audio codec. Biostar also isn’t clear in its official specifications about the validity of its M.2 slots, as it advertises two PCIe 4.0 x4 M.2 slots, but this is really unlikely to be the case. At present, Biostar hasn’t unveiled any information in regards to pricing.

Most of these boards are a serious VRM upgrade over the B450 boards. If I was buying Ryzen right now I'd easily go B550 over X570.So, only the ASUS boards offer bios flashback? Seems like a cheaper, just as userful version of dual BIOS anyway.

Finally ONE mini-ITX board with 3-monitor output.Gigaplex - Tuesday, June 16, 2020 - link
Colour me disappointed. I was hoping to do a mATX file server build using an APU. No support for existing APUs, no ETA on when consumers can buy the newer APUs, and most of these boards only have 4 SATA ports.I really don't want to have to buy a crappy NVIDIA 710 just to get it running.

If you're booting Linux, you might be able to get away with either a good old fashioned serial cable (a lot of boards still have a serial port header) or a USB-HDMI/VGA dongle, since these are supported by the mainline kernel. The main issue might jus tbe getting the BIOS to boot your install media, but a serial port might work still here.You could also just borrow a graphics card from any other system you own to do the initial install, and then let it run headlessly once it's up and running.

I am booting Linux, and have tried completely headless in the past. It's not really worth the trouble (especially if I need to quickly diagnose issues), I'd rather just buy the crappy GPU.IBM760XL - Tuesday, June 16, 2020 - link
I'm probably missing something, but what's the point of including HDMI/DP/DVI outputs if the boards don't support APUs? Aren't you going to need to use the output on your dGPU anyway?I appreciate the summaries on the last page, but wish it could be enhanced a bit. E.g. what's the cheapest board with 2.5G Ethernet? What are the cheapest boards in general? I probably wouldn't go with the cheapest one, but given the prices on a lot of these, it's likely I would choose one of the less expensive ones.

They will support the Zen 2 APUs, which aren't out yet.IBM760XL - Tuesday, June 16, 2020 - link
So checking my local store's inventory, they have 25 B550 boards in stock, of all varieties, but are completely sold out of both B450 and X570 (there are a few cheap A320 boards available as well, and nine TRX40 boards that start at $450).Something tells me Ryzen 3000 chips have been selling quicker than the motherboard manufacturers can keep up, and maybe that's part of the reason B550 prices are starting out high. If they're selling out, it makes sense for them to start with a higher MSRP, which they can always lower if demand falls.
Unfortunately for AMD, if B450 doesn't come back in stock, that's going to hurt Ryzen 3000 sales. Intel mobo inventory is also a bit limited, but about half of the Intel models they offer are available, including some in that $75-$125 range, versus about 15% of the AMD models being in stock currently.

I think the delays are all shipping-related. It's affecting all computer parts, like power supplies, motherboards, and the like. I wish a bunch of the mfgs would just pool resources to buy dedicated air cargo flights; maybe pooling will mitigate some of the losses on the lower margin items.Oxford Guy - Tuesday, June 16, 2020 - link
"Most of these boards are a serious VRM upgrade over the B450 boards. If I was buying Ryzen right now I'd easily go B550 over X570."Why does that matter? Overclocking died with Zen, especially Zen 2.
As long as it doesn't throttle, you're good.
