AMD on Thursday confirmed that the next-generation AMD Ryzen desktop processors, which will use the Zen 3 architecture, will be fully compatible with the AMD X570 and the B550 motherboards. That’s great news because enthusiasts have a viable upgrade path that does not involve buying additional basic hardware just to get a CPU upgrade.
The confirmation came from a revised roadmap that now describes support for the Zen 3 on the aforementioned chipset. In announcing the compatibility, AMD said it would need a BIOS update but that was a small hurdle to overcome in exchange for not having to buy a new motherboard.
AMD’s X570 chipset has been around since last summer. The B550, meanwhile, was officially introduced last month with two new Ryzen 3 chips – the Ryzen 3 3100 and the Ryzen 3 3300X. These two processes will arrive on May 21 at $ 99 and $ 120, respectively.
All that said, AMD noted that it has no plans to introduce Zen 3 architectural support for older (X pre-500 Series) chipsets. The company said it wants to enable full support for each processor on each chipset but the flash memory chips that store BIOS settings have capacity limitations.
Because of these limitations and the unprecedented stretch of the AM4 socket (this is from late 2016), AMD says that inevitably will be a time when they need to make a move and the 500 Series chipset is time that.
Update: As many readers have pointed out in the comments, this is AMD’s official support list guaranteed. It is entirely possible for motherboard manufacturers to expand here, by providing Zen 3 support with the existing AMD X470 and B450 motherboards, for example.
This is what happened when a number of X370 motherboards received support for the Ryzen 3000 through BIOS updates, though AMD has yet to officially support it. We will know if we know, but it is important to remember it.
