QuoteFor the past 30 years, PCI-SIG® has been at the forefront of technology innovation. Our PCI Express® (PCIe®) specification has maintained its position as the established de-facto interconnect of choice and a crucial component of the compute continuum. At the PCI-SIG Developers Conference 2022, we celebrated our 30-year anniversary with the announcement of the next evolution of PCIe technology: PCIe 7.0 specification. The forthcoming PCIe 7.0 specification is planned to once again deliver a speed increase in three years, expanding the data rate of the recently released PCIe 6.0 specification to 128 GT/s. The PCIe 7.0 specification 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 (GigaTransfers per second)) 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
