When building a new PC, longevity and upgradability of components are often at the forefront of the purchasing process. AMD has historically given its chipset platforms a long life, with numerous upgrades over time. AMD's AM5 platform appears to be no exception, with recent BIOS updates from ASUS and MSI all but confirming compatibility with AMD's next-gen CPUs. AMD's Zen 5 Ryzen 9000 series appears to be supported, allowing for a painless drop-in upgrade for existing users.
The AGESA version is now Combo AM5 P1 1.1.7.0 Patch A, released for a variety of AMD 600 series motherboards for both ASUS and MSI. Other vendors surely will follow, as we can expect with the eventual release.
The current AM5 Ryzen 7000 series has been popular, but it started off life at a snail's pace. The initial release of AMD's AM4 Ryzen 5000 CPUs rocketed AMD to the most dominant position in gaming CPUs, eclipsing Intel. They had the benefit of being a drop-in upgrade for AMD AM4 motherboard owners, such as X570 motherboards.
With the introduction of AMD's Ryzen 7000 lineup, an entirely new platform was also needed with AM5. This carried with it the requirement for DDR5 RAM, which was at the time more expensive than widely available DDR4.
AMD's AM5 platform has matured, however, and is brimming with success with CPUs such as the AMD Ryzen 7 7800X3D. Therefore, with owners already possessing the requisite DDR5 and AM5 motherboards, it is sensible the next generation will be a drop-in upgrade.
