Pci

PCIe 4.0 has barely hit the streets, but PCI-SIG is ready for the future of this interface, taking the PCI Express standard to new levels, doubling the bandwidth it offers with PCI Express 5.0, which has already been officially launched.

PCI Express 5.0 will offer twice the bandwidth of PCIe 4.0

PCIe 5.0 comes just 18 months after the release of PCIe 4.0, and the standard's release comes shortly after the introduction of several products that support PCI Express 4.0. With this new iteration, PCI Express is able to offer a 4x per lane bandwidth advantage over current PCI Express 3.0 products, offering outstanding bandwidth levels.

Here are some highlights from the PCI Express 5.0 standard:

• It offers a gross bit rate of 32 GT / s and up to 128 GB / s through the x16 configuration. Take advantage of and add to the PCIe 4.0 specification and its compatibility with higher speeds through tags and extended credits. PCI Express 5.0 implements electrical changes to improve signal integrity and connector performance. Includes new EMC connector backward compatible for add-in cards Maintains compatibility with PCIe 4.0, 3.x, 2.x and 1.x.

PCI-SIG has enabled devices on par with Samsung's 970 Pro SSDs to run on a single PCIe 5.0 track, rather than four PCIe 3.0 tracks, allowing devices to be up to four times faster, or up to four times more equivalent devices can be used.

PCIe 5.0 is expected to hit mass hardware starting in 2021.
