2021年中AMD的CPU主力依然會是Ryzen 5000系列，7nm Zen3不論性能還是功耗目前都還是有優勢的，5nm Zen4要等2022年了。
at the same time，AMD在主機板升級上也是公認的良心，These generations of Ryzen use the AM4 socket，Ryzen 5000系列除了500系主板之外還可以支持去年的400系主板，The manufacturer's BIOS upgrade has long been completed。
Earlier 300-series chipsets，ASRock、Asus and other manufacturers have also promised to upgrade the BIOS before，加入Ryzen 5000系列的支持，BIOS has already been released。
However, it has been reported in the past two days that，AMD Surprisingly Starts Blocking Manufacturers from Upgrading X370 and A320 Motherboards，不希望這些平台支持Ryzen 5000處理器。
現在的問題就尷尬了，The new BIOS version of X370 released by the manufacturer has not been finalized yet，Previously published or beta version，Now AMD has come forward to oppose，It may be difficult for motherboard manufacturers to continue to improve the BIOS.。
The reason why AMD blocked X370 and other motherboards from supporting Ryzen 5000 is unknown，Most likely technical limitations，Previously, AMD restricted the use of older motherboards，including B350、X370、PCIe 4.0 support for B450，saying doing so would create confusion and risk。
