PCI-SIG Announces PCI Express 7.0 Specification to Reach 128 GT/s

PCI-SIG today announced that the PCI Express (PCIe) 7.0 specification will double the data rate to 128 GT/s [gigatransfers per second] and is targeted for release to members in 2025.

PCI-SIG technical workgroups will be developing the PCIe 7.0 specification with the following feature goals:

• Delivering 128 GT/s raw bit rate and up to 512 GB/s bi-directionally via x16 configuration
• Utilizing PAM4 (Pulse Amplitude Modulation with 4 levels) signaling
• Focusing on the channel parameters and reach
• Continuing to deliver the low-latency and high-reliability targets
• Improving power efficiency
• Maintaining backwards compatibility with all previous generations of PCIe technology
