For the two x86 CPU manufacturers, the compatibility of the new generation CPU will be a sensitive topic. Amd promised that the AM4 slot will be used in 2020, which won fans' favor.But after the b550 chipset was launched a few days ago, amd unexpectedly announced that zen3 can only support x570, b550 and other new generation motherboards in the future.

Prior to the 500 mainboards, the AMD had 300 and 400 platforms, including X370、B350、A320、X470 and B450,, which were still not on stage. They could theoretically support Zen3 processors by the end of the year, as promised before the AMD.

But AMD changed his mind, rearranged chipset compatibility,The future zen3 processor needs platforms such as x570 and b550, and is no longer compatible with 300 and 400 series chipsets.

This event was discussed enthusiastically in overseas communities. There were many criticisms on AMD. Users of 300 and 400 series motherboards felt betrayed.


For AMD's decision, YT broadcaster tech deals learned from anonymous amd employees,It is not a technical reason for AMD to change the compatibility of AM4 platform, but a commercial consideration. There is no problem for 300 and 400 series motherboards to support zen3 processor in theory.

Of course, in fact, we all know that AMD's decision is not based on technical restrictions, but on the interests of itself and the motherboard manufacturers. After all, long-term downward compatibility will result in no power for us to upgrade the new platform. How can technology like PCIe 4.0 be popularized?

With this in mind, the future does not rule out motherboard manufacturers low-key low-key on the 300,400-series motherboard attempt to crack the limit, let them support the Zen3 processor, it will be AMD attitude.
