Ask the Experts: An Interactive Discussion about the PCI Express® 6.0 Specification


Authors: Debendra Das Sharma (Peripheral Component Interconnect Special Interest Group (PCI-SIG), Intel Corporation), Richard Solomon (Peripheral Component Interconnect Special Interest Group (PCI-SIG), Synopsys Inc)

Abstract: PCI-SIG® has consistently delivered enhanced performance, unprecedented speeds, and low latency with each new PCI Express® specification release. The PCIe® 6.0 specification delivers 64 GT/s data rate (256 GB/s via x16 configuration), while maintaining full backward compatibility with previous generations of PCIe technology.

In this interactive session, attendees will learn from the experts how PCIe 6.0 architecture enables next-generation HPC applications, like artificial intelligence, machine learning, and deep learning. This session will also highlight PCIe 6.0 technology use cases, the diverse HPC applications that will be accelerated by PCIe 6.0 technology, and a look toward the future of PCIe technology.


Long Description: PCI-SIG® continues to evolve the PCI Express® (PCIe®) architecture with the PCIe 6.0 specification. Scheduled for final release this year, the PCIe 6.0 specification delivers the fastest data rate yet at 64 GT/s (up to 256 GB/s via x16 configuration), doubling the bandwidth of the PCIe 5.0 specification while maintaining full backwards compatibility with previous generations. PCIe 6.0 technology redefines the fabric, adding PAM4 (pulse amplitude modulation) signaling, FLIT-based encoding and low-latency Forward Error Correction (FEC). These new features allow for low latency, minimal complexity and limited bandwidth overhead. PCIe 6.0 technology is a cost-effective and scalable interconnect solution for data-intensive markets including artificial intelligence and machine learning, data center networking, HPC and Internet of Things (IoT). The PCIe 6.0 specification continues to meet industry demand, while adding new features and improvements to maintain high speed and low latency for years to come. This interactive session includes brief technical presentations from PCI Express technology experts. In the first presentation, PCI-SIG® Board Member Debendra Das Sharma will provide an overview of the “nuts and bolts” of PCIe 6.0 technology and how PCI-SIG was able to achieve data rates of 64 GT/s without sacrificing signal integrity. In the following presentation, PCI-SIG Vice President Richard Solomon will discuss the various use cases and applications that will be accelerated by PCIe 6.0 technology, provide an update on the upcoming compliance program and a look toward the future of PCIe technology. Following each presentation, audience members will have the opportunity to “ask the experts” questions about the PCIe 6.0 specification and participate in the discussion. The intention of this session is to facilitate a round table discussion where all points of view are considered. Please note that presenters will not be able to answer questions about individual companies’ plans involving PCIe technology. PCIe technology has experienced massive adoptions rates and served as the de facto interconnect of choice for nearly three decades. This session is an excellent opportunity for system developers and engineers interested in learning more about the next-gen features of the PCIe 6.0 specification to chat with industry experts in a relaxed setting.
