BEAVERTON, Ore.--(BUSINESS WIRE)--PCI-SIG® today announced the release of PCI Express® (PCIe®) 5.0 specification, reaching 32GT/s transfer rates, while maintaining low power and backwards compatibility with previous technology generations.
“New data-intensive applications are driving demand for unprecedented levels of performance,” said Al Yanes, PCI-SIG Chairman and President. “Completing the PCIe 5.0 specification in 18 months is a major achievement, and it is due to the commitment of our members who worked diligently to evolve PCIe technology to meet the performance needs of the industry. The PCIe architecture will continue to stand as the defacto standard for high performance I/O for the foreseeable future.”
“For 27 years, the PCI-SIG has continually delivered new versions of I/O standards that enable designers to accommodate the never-ending increases in bandwidth required for next generation systems, while preserving investments in prior generation interfaces and software,” noted Nathan Brookwood, research fellow at Insight 64. “Over that period, peak bandwidth has increased from 133 MB/second (for the first 32-bit parallel version) to 32 GB/second (for the V4.0 by16 serial version), a 240X improvement. Wow! The new PCIe 5.0 standard doubles that again to 64 GB/second. Wow2. We have come to take this increased performance for granted, but in reality, it takes a coordinated effort across many members of the PCI-SIG to execute these transitions so seamlessly.”
PCIe 5.0 Specification Highlights
- Delivers 32 GT/s raw bit rate and up to 128 GB/s via x16 configuration
- Leverages and adds to the PCIe 4.0 specification and its support for higher speeds via extended tags and credits
- Implements electrical changes to improve signal integrity and mechanical performance of connectors
- Includes new backwards compatible CEM connector targeted for add-in cards
- Maintains backwards compatibility with PCIe 4.0, 3.x, 2.x and 1.x
The new specification increases performance in the high-performance markets including artificial intelligence, machine learning, gaming, visual computing, storage and networking.

Silicon Labs
“One of the outstanding features of the PCI Express 5.0 specification that sets it apart from other communication standards is the inclusion of the Refclk performance in the specification. By fine tuning various system parameters to minimize the amount of reference clock noise that contributes to data transmission eye closure, PCI-SIG has been able to retain lower cost reference clock technology than competing standards at similar data rates. In addition, because PCI-SIG specifies the reference clock performance as part of the standard, companies like Silicon Labs which supply PCI Express technology reference clocks for a variety of applications, can further reduce cost by consolidating volume across multiple customers even though they use PCIe transceivers from different vendors.”
~Greg Richmond, Director of Engineering for Silicon Labs and contributing member of the PCI-SIG® Electrical Working Group, Silicon Labs
