https://www.techpowerup.com/267344/55-amd-b550-chipset-motherboard-model-names-revealed Model names of 55 motherboards based on the AMD B550 chipset were leaked to the web by momomo_us. In an unexpected surprise, it turns out that ASRock will have the largest lineup of motherboards, with 15 models. ASRock's lineup will be led by a premium Taichi model (
already pictured), but will also include a Phantom Gaming Velocita model, besides Extreme4 and Steel Legend. MSI has the second largest lineup, with 14 models. There's a surprise here.
We earlier thought the MPG B550 Gaming Carbon will lead MSI's lineup, but it turns out that there will be a MEG B550 Unify model at the top. The rest of the lineup includes MPG Gaming Edge, MAG Tomahawk, MAG Mortar, and MAG Bazooka. GIGABYTE has the third largest lineup, with 12 models. The series is led by an AORUS Master model. There are several other AORUS Gaming SKUs based on this chipset - PRO, Elite, and their Mini-ITX variants. ASUS plans to bring 11 SKUs to the table, including four ROG Strix series boards that include Strix-E, Strix-F, and the Mini-ITX Strix-I. There are also three TUF Gaming SKUs, while the rest of the lineup is made up of the vanilla Prime series. Biostar has two models, and so does SOYO. AMD is expected to launch its B550 chipset in mid-June.
Looks like a lot of support from OEMs for this chipset in my opinion.
