We caught up with PCI-SIG, the organization that defines the PCI Express bus and form factor specifications, at the yearly Hot Chips conference.  PCIe is the ubiquitous engine that pulls a big part of the computing locomotive down the track—it touches nearly every device in your computer. As such, it is the linchpin for the development of many other technologies, such as storage, networking, GPUs, chipsets, and many other devices.

Considering its importance, it isn’t surprising to find the PCI-SIG with 750 members worldwide. Unfortunately, large organizations tend to move slowly, and PCIe 4.0 is undoubtedly late to market. PCIe 3.0 debuted in 2010 within the normal four-year cadence, but PCIe 4.0 isn’t projected to land in significant quantities until the end of 2017—a seven-year gap.
