The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Others
by Dr. Ian Cutress & Gavin Bonshor on June 16, 2020 11:00 AM ESTBiostar Racing B550GTQ
In addition to its ATX sized B550GTA, the Biostar Racing B550GTQ is a micro-ATX sized model with the same design and near-identical feature set of its larger sibling. Looking more like an entry-level offering, the biggest features include a pair of M.2 slots, six SATA ports, a Realtek Gigabit Ethernet controller and a Realtek ALC1150 HD audio codec.
Following a consistent black and grey theme throughout, the Biostar Racing B550GTQ is a micro-ATX model and includes two full-length PCIe slots. This includes the top slot which runs at PCIe 4.0 x16, while the second slot is locked to PCIe 3.0 x4. Complementing the full-length slots is a pair of PCIe 3.0 x1 slots. The board's storage consists of two PCIe slots and although Biostar is advertising both to feature support for PCIe 4.0 x4, it’s likely that only one of these will support Gen4, with the other supporting up to PCIe 3.0 x4 drives. There are also six SATA ports, with four right-angled and two straight-angled ports. The B550GTQ has four available memory slots, with support for up to DDR4-4400, with a maximum capacity of up to 128 GB.
The rear panel includes a single USB 3.2 G2 Type-C, one USB 3.2 G2 Type-A, four USB 3.2 G1 Type-A, and two USB 2.0 ports. Powering the single RJ45 port is a Realtek RTL8118AS Gigabit Ethernet controller, while the boards three 3.5 mm audio jacks are controlled by a Realtek ALC1150 HD audio codec. Biostar has included three video outputs with DVI-D, HDMI and DisplayPort, which gives users plenty of VGA options to consider if pairing up this board with a Ryzen APU. Finishing off the rear panel is a PS/2 keyboard and mouse combo port.
Biostar hasn’t unveiled pricing at present for either of its B550 models, but it’s likely the B550GTQ will cost under $100 based on the feature set in comparison to what other vendors are offering. Biostar is consistently using an older Realtek ALC1150 HD audio which was commonly found on motherboards around five years ago.

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.
