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.

I've read elsewhere that Zen1 processors supposedly had a 128 Mb address limit for UEFI firmware. It sounds suspect, but looking back at early AM4 boards, I don't recall any with either 256 Mb chips or striped 128 Mb chips, so maybe it wasn't simply due to the significant jump in price for 256 Mb chips over 128 Mb ones.Redstorm - Tuesday, June 16, 2020 - link
Likewise, looking to replace my aging 7 year old HTPC with a mATX B550 and a Ryzen 4700G but radio silence from AMD on releasing compatiable APU's for the B550's, We now have the long overdue Budget motherboards but no APU's. Dissapointed.alufan - Wednesday, June 17, 2020 - link
I understand the frustration however if your buying a Budget Board then surely a budget CPU is the best fit, also new APUs are inbound according to all the rumours, meanwhile your older APU will fit just fine I believe, I expect the new APUs will have Navi cores as per the Xbox and PS5 but of course they probably cannot be released until the new Navi cards and consoles are out, think about it though what a sea chamge folks are now waiting eagerly for a new release from AMD because they know it will kick ass not close the gap to Intel, its a good time to be a customer!Gigaplex - Wednesday, June 17, 2020 - link
Older APUs aren't supported on B550DigitalFreak - Tuesday, June 16, 2020 - link
I think you forgot something... :-)Fortunately, this component is a unique motherboard among B550 and well worth reading up on [add link].

Interesting that the GIGABYTE B550 Vision D board's Type-C ports don't have the Thunderbolt logo next to them. I wonder if Intel won't all the logo to be use on AMD systems.DigitalFreak - Tuesday, June 16, 2020 - link

"Although on paper, there isn't much difference between B450 and B550 with slightly more SATA available due to the removable of eSATA support, both remain PCIe 3.0 bound."The B450 only had PCIe 2.0 lanes. Huge difference from the B550 IMO

Agreed. That's going to make a huge difference for boards with secondary or tertiary M.2 or U.2 ports that hangs off the chipset. That goes double if they only get 2 PCIe lanes instead of the full 4.a5cent - Friday, June 19, 2020 - link
Yup, exactly what I thought.Equally "BIG" is that B550 finally has more PCIe lanes, so adding more NVMe drives doesn't require downgrading other ports like it always did on B450.
B450 was a firmware upgrade for the budget B350 chipset. B550 is the first time this tier of AMD chipset doesn't suck.
