PCI Express 4.0 motherboards, Solid State Drives. and other devices are not widely available yet, but that has not stopped the Peripheral Component Interconnect Special Interest Group (PCI-SIG) from releasing PCI Express 5.0 specifications on May 29, 2019.

Compared to PCI Express 4.0, PCI Express 5.0 promises double the bandwidth and other improvements while maintaining backwards compatibility with existing PCI Express peripherals.

PCI Express 4.0 doubled the bandwidth, frequency, and transfer rate of PCIe 3.0, and PCI Express 5.0 is designed to quadruple it.

Target markets for PCI Express 5.0 include gaming, visual computing, AI, storage, and machine learning.

The new specification increases performance in the high-performance markets including artificial intelligence, machine learning, gaming, visual computing, storage and networking.

Tools like HwInfo or CPU-Z may help you find out which PCI Express standards the PC you run this on supports (if any).

PCI Express 5.0 specification details

* Bandwidth of 128 GB/s, 32 GT/s, 32.0 GHz frequency, and 128b/130b encoding.
* Backwards compatible with all major PCI Express standards (4.0, 3.x, 2.x, and 1.x).
* Features new backwards compatible CEM connector for add-in cards.
* Support for extended tags and credits.
* Electrical changes improve signal integrity and mechanical performance of connectors.
