AMD is still maintaining a performance embargo for its mid-range B450 chipset, but that hasn't stopped its hardware partners from releasing information about their specific products. We've also spotted some B450 motherboards selling on Newegg.

The B450 chipset supplants AMD's previous generation B350 chipset and adds some new features. Notably, the newer chipset adds support for AMD's XFR2 Enhanced and Precision Boost Overdrive technologies that are found on the company's second-generation Ryzen processors.
