The PCIe 6.0 architecture also maintains compatibility with all previous generations of PCIe. That will allow any existing hardware that uses earlier specifications to work in PCIe 6.0 hosts, and it will certainly help with adoption and the transition to this new specification.
While PCIe 5.0 is still in its infancy and being demonstrated with enterprise-grade SSDs, we shouldn’t expect to see PCIe 6.0 hardware for another 12 to 18 months. That means some servers will likely start to use the new spec at some point in 2023, with consumer hardware to follow in 2024 or 2025. Until then, get ready to hear a lot more about PCIe 5.0 SSDs, GPUs, and more throughout 2022.
