PCIe 6.0 Specification Features

  • Delivers 64 GT/s raw bit rate and up to 256 GB/s via x16 configuration
  • Utilizes PAM-4 (Pulse Amplitude Modulation with 4 levels) encoding and
    leverages existing 56G PAM-4 in the industry
  • Includes low-latency Forward Error Correction (FEC) with additional
    mechanisms to improve bandwidth efficiency
  • Maintains backwards compatibility with all previous generations of
    PCIe technology

“PCI Express technology has established itself as a pervasive I/O
technology by sustaining bandwidth improvements for five generations
over two decades,” Dennis Martin, an analyst at Principled Technologies,
said. “With the PCIe 6.0 specification, PCI-SIG aims to answer the
demands of such hot markets as Artificial Intelligence, Machine
Learning, networking, communication systems, storage, High-Performance
Computing, and more.”

“Continuing the trend we set with the PCIe 5.0 specification, the PCIe
6.0 specification is on a fast timeline,” Al Yanes, PCI-SIG Chairman and
President, said. “Due to the continued commitment of our member
companies, we are on pace to double the bandwidth yet again in a time
frame that will meet industry demand for throughput.”
