Navedene specifikacije na AMD B550 Chipset Surface

We've known for some time that AMD's mainstream-segment B550 chipset wouldn't bring all the bangs and whistles of its bigger, enthusiast-class cousin X570. For one, it wouldn't make sense to increase development and implementation costs of both the chipset and motherboards built for mainstream enthusiasts by adding PCIe 4.0 support and the more stringent signaling and power requirements the new standard entails. As such, B550 reportedly cuts down fully on PCIe 4.0 support, as well as on the latest USB standards, to offer a product that's sufficiently rounded up on I/O while offering overclocking support for users that demand it.

Navodno će AMD-ov B550 podržavati samo do 2x USB 3.2 Gen2 uređaja, 6x USB 2.0, 4 + 4 SATA3 veze, a međusobno povezivanje čipseta i CPU-a dolazi putem 4x PCIe 3.0 sučelja, što znači da je manja propusnost za komunikaciju između CPU i čipset nego na X570 - nije da je to bio pravi problem na AMD-ovim proizvodima Ryzen prethodnog roda, doduše, tako da je to u ovom trenutku više tehnička stvar. Ryzen 3000 CPU-ovi i dalje nude 4x PCIe 4.0 portove, pa bi se, primjerice, mogli koristiti za ubrzanje PCIe 4.0 NVMe SSD-a. Lansiranje proizvoda vezanih uz B550 očekuje se prema listopadu.
