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

> x1 should allow for up to 121 Gbps
I wonder if the processors can keep up (yeah, DMA is a thing, but there is still a lot that has to go through the processor).
I guess the low power ARM stuff can forever stick with pcie gen 3 and gen 2.
