It seems like AMD won’t be able to stay true to its initial promise of supporting all previous Ryzen CPUs on the brand new 3rd Gen X570 platform, at least not completely. So, it turns out that the first gen Zen-based chips, both Summit Ridge as well as Raven Ridge won’t be supported by the new chipset, at all. The A320 will definitely not be compatible with the new Ryzen 3000 processors (ever), while the decision to make B320 and X370-based boards Zen 2 ready will vary from manufacturer to manufacturer.

If we look across the ecosystem of motherboards that exist today, we certainly make BIOS updates available to our ecosystem partners to include that on different levels of motherboards in their portfolio, but I don’t expect that every motherboard will be updated for 3000 Series processors from our partners. That really will be a portfolio decision from their standpoint as well, as to where they apply those updates, and where they choose not to apply those updates.

On the bright side, the X470 and B450 chipsets will support all three generations of the Ryzen processors, right from the 14nm Zen to the 7nm Zen 2 parts. This is still way more consumer-friendly than any of Intel’s architectures where the general trend dictates that every new generation will require a new chipset, regardless of whether there’s any actual difference between the two.
