PCI-SIG shared today that the PCI Express 7.0 v0.9 specification is now available for member review. No further functional changes are expected for PCIe 7.0 and the spec is on track for publishing later in 2025.



As a reminder of the key features of PCI Express 7.0:
- 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
- Improving power efficiency
- Continuing to deliver the low-latency and high-reliability targets
- Maintaining backwards compatibility with all previous generations of PCIe technology

SD 8.0 specification provides two transfer speed options for SD Express memory cards with either:

PCIe 3.0 x2 or PCIe 4.0 x1 architectures for up to ~2GB/s sequential data transfer
PCIe 4.0 x2 technology for up to 4GB/s transfer rate.
