AMD Chipset Differences: B550 Specs Explained vs. X570, B450, & Zen 3 Support (2020)

AMD's B550 chipset has a release date set for June 16. We're comparing AMD's chipsets and talking about differences between X570, B550, B450, X370, and A320, plus Zen 3 support.

AMD's chipset naming convention hasn't changed much over the years, but the company hasn't really produced a single public source of validated, detailed information on the AMD B550 chipset specs, particularly as it compares vs. X570. We'll be covering I/O differences with hard numbers for X570 vs. B550, X470, B450, and A320M. Using AMD's latest information release to press, we can also talk about planned support for future AMD Zen 3 CPUs on the 500-series, as currently X470 and B450 aren't advertised as supporting Zen 3, and we can also look at backwards compatibility for the new AMD chipsets. The differences in the chipsets primarily boil-down to PCIe generational differences, so that'd be Gen4 support for both the CPU and chipset lanes, Gen3 general purpose lanes, and Gen2 general purpose lanes on the older platforms.
