PCI-SIG has detailed the PCI Express 4.0 specification at its 2017 Developers Conference.
PCI-SIG is the industry group which controls the PCI Express standard that is used across a variety of form factors, including Thunderbolt 3 and M.2.
The group planned to launch its fourth-generation PCIe specification in 2015, but it was delayed until this year.
PCIe 4.0 will provide a 16GT/s bit rate, doubling the bandwidth of the PCIe 3.0 configuration, while remaining backwards compatible with previous standards.
PCI Express has become ubiquitous across numerous devices and is used as an interconnect for many components.
The fourth gen of PCI Express will also feature reduced system latency and support for added lanes and lane margining.
PCI-SIG said its PCIe 4.0 specification is ready to be implemented and will undergo a final review before launch.
