Quote:The PCI Express 3.0 standard has been with us rather longer than anyone intended it to be. The standard was initially finished in 2010, and motherboards supporting it were in-market by 2011. PCI Express 4.0 should have been available by 2013 if the organization had kept to its previous pace, but delays and difficulties associated with the design have left PCIe 4.0 support languishing. Now PCI-SIG has announced that PCIe 4.0 specification is finished — and it plans to have PCIe 5.0 ready to go by 2019.
That’s an accelerated launch window and, given the relatively short window between completing the standard and shipping hardware (typically about 12 months), it’s not clear if PCIe 4.0 will find a huge home in the market. PCIe 5.0, according to the standards body, is coming along quite quickly.

A quick progression from PCIe 4.0 to 5.0 might result in consumer hardware not shipping PCIe 4.0 for very long, but the 4x bandwidth increase for peripherals and devices would be huge.
