PCI-SIG® Fast Tracks Evolution to 32GT/s with PCI Express 5.0 Architecture

PCI-SIG Developers Conference 2017, Santa Clara, CA. – June 7, 2017 - PCI-SIG®, the organization responsible for the widely adopted PCI Express® (PCIe®) industry-standard input/output (I/O) technology, today announced 32GT/s as the next progression in speed for the PCIe 5.0 architecture, targeting high-performance applications such as artificial intelligence, machine learning, gaming, visual computing, storage and networking. Slated for completion in 2019, the specification development is well underway with Revision 0.3 already available to PCI-SIG member companies.

“In our 25-year history, PCI-SIG has maintained its commitment to our rigorous specification development process, while delivering specifications that are in lock-step with industry requirements for high-performance I/O,” said Al Yanes, PCI-SIG Chairman and President. “PCIe 5.0 technology is the next evolution that will set the standard for speed, and we are confident that its 32GT/s bandwidth will surpass industry needs.”

The preceding PCIe 4.0 specification is designed with key functional enhancements that future-proof the PCIe architecture design, thereby accelerating future specification development. This undertaking, along with improved silicon design processes, serves as the foundation for the PCIe 5.0 specification.

For high-end networking like 400Gb Ethernet solutions and dual 200Gb/s InfiniBand, the PCIe 5.0 architecture operates at full duplex and provides up to 128GB/s in bandwidth. The higher bandwidth will serve accelerator and GPU attachments, as well as constricted form factor applications needing to increase channel width.

“With the onset of Big Data and the magnitude of high-performance applications, the storage industry has had to restructure bandwidth provisioning and deployment,” said Amber Huffman, NVM Express President. “This restructuring was accelerated thanks to the scalability and low-latency offerings of the PCIe architecture, which NVMe has leveraged as the interface for SSDs in the datacenter and enterprise. We’re pleased to see PCI-SIG continue to evolve this important technology.”

“Over the past 10 months, PCIe 4.0 adoption by PLDA customers from the servers, networking and storage industry has massively started. The PCIe 5.0 announcement timing is great and will enable PLDA and its customers to start working together and defining the next generation products roadmap.”
