AMD introduced the B550 chipset as part of their Spring 2020 desktop Ryzen update, offering PCI Express 4.0 support at a lower price point. Here is what you need to know!
AMD B550 Chipset : Official Tech Briefing
Let’s start with the official AMD B550 tech briefing by AMD Ryzen Product Marketing Manager, Erin Maiorino.
AMD B550 Chipset : Key Features
The AMD B550 chipset is an upgrade of the B450 chipset from 18 months ago, introducing three key features :
- PCI Express 4.0 support for both graphics cards and NVMe storage
- Dual GPU support
- PCI Express 3.0 general purpose lanes
This AMD table gives you a good idea of what the B550 chipset offers over the B450, and how it differs from the X570.
It is obvious that unless you use multiple NVMe SSDs in your system, the new AMD B550 will offer a much better value proposition than the X570.
This diagram shows what PCI Express lanes and USB ports are available through the B550 chipset, and the 3rd Gen Ryzen processor.
While AMD has been rather decent in providing backward compatibility for their newer Ryzen processors, eventually a chipset will not sufficiently support a newer processor.
Like the X570, the new B550 chipset will support future AMD Ryzen processors based on the Zen 3 microarchitecture.
AMD B550 Motherboard : Availability
AMD says that their partners have some 60 motherboard designs in the pipeline, and that you should expect some B550 motherboards to ship by 16 June 2020.
