PCIe 5.0 beginning to come to new PCs, but version 6.0 already here
Posted: 13 Jan 2022
The PCI Special Interest Group (PCI-SIG) has finalized version 6.0 of the PCI Express standard, the communication bus that lets all the stuff inside your computer communicate. The new version of the spec comes roughly three years after the PCI Express 5.0 spec was finalized, and version 6.0 once again doubles the bandwidth of a PCIe lane from 32GT/s (8GB/s in total, or 4GB/s in each direction) to 64GT/s (16GB/s, or 8GB/s in each direction). For a full 16-lane PCIe 6.0 connection, that's as much as 256GB/s of total bandwidth, compared to the 32GB/s or 64GB/s of now-common PCIe 3.0 and 4.0 connections.
