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

Possibly not. GPUs are getting to where they don't need the bandwidth that's already available, and it seems like SSDs are nearing that point as well.
It might be that these high speed interconnects end up only being useful in data centers. But, if the bandwidth is available, maybe someone will find a use for it that no one has thought of yet.
