Discussion about the Ryzen X570 processor
PCIe 4.0 requires a processor from the third generation to function properly.
In short, all x570 chips will work with Ryzen 2nd and 3rd series models. The earlier Ryzen and pre-Zen designs won’t be compatible. PCI-e 4.0 requires processors that recognize it, which means only the 3rd gen Ryzen with Zen 2 cores can use it—except for those with built-in graphics, which still use Zen+ cores.
