PCI-SIG has announced the specifications for the PCIe 6.0 standard even as PCIe 4.0 devices are yet to become available in the market. PCIe 6.0 will offer double the bandwidth of PCIe 5.0 and uses a PAM-4 signal modulation technique to allow for increased data transfer in the same amount of time. PCIe 6.0 will continue to be backward-compatible with all existing PCIe standards and is expected to land in 2021.
