AMD 400-series motherboards are coming

The refresh of the first-generation Ryzen is currently expected in the first quarter next year. Although new CPUs will certainly be compatible with 300-series motherboards, AMD is giving a chance to their partners to refresh their motherboard offering with X470, B450, A420 series.

The Zen+/Ryzen 2000, also known as Pinnacle Ridge, is a 12nm upgrade of Zen1. We expect higher clock speeds and better power efficiency. Meanwhile, Zen2, which might be used for Ryzen 3000 series, is said to deliver bigger changes to Zen architecture as we approach 7nm fabrication process.

The Promontory platform, which is a codename for Summit Ridge 300 series chipsets, has been listed at PCI-SIG since January 2016. However, for the first time, it was also listed as a codename for ‘400-Series Chipsets’.
