There are rumors that motherboard manufacturers already have some CPUs and are in the validation phase of the current motherboards while developing the first X570 motherboards in parallel. Keep in mind that multiple motherboards should be compatible, and even some X470 may support PCI-E 4.0, so these issues may be validated. In this case, users simply need to update the BIOS and place their new CPU without touching anything else.
This week, Asus and MSI released the new AGESA 0070 and 0072 BIOSes on their X370 and X470 motherboards, which are designed to support the new AMD CPUs.
These new CPUs, internally known as Valhalla, are expected to have up to 16 cores and 32 threads in the new Ryzen 9 line and will be released in late May or early June near Computex. They are manufactured at 7nm and are based on the Zen2 architecture, which represents a high-performance leap over the current generation.
