Announcement on April 3rd: The official organization PCI SIG has declared the completion of the full draft version 0.5 of the PCIe 7.0 standard specification, which has been issued to organization members for evaluation, encompassing all changes of PCIe 7.0.
PCI SIG further emphasizes that the PCIe 7.0 specification is slated for official release in 2025 as planned.
Looking back, PCIe 4.0 debuted in October 2017, PCIe 5.0 was officially announced in May 2019, and PCIe 6.0 was born in January 2022, maintaining a pace of roughly a new generation every two to three years.
Following its design trajectory, PCIe 7.0 is set to evolve further on the significant changes introduced in PCIe 6.0. Bandwidth will once again double, reaching up to 512GB/s in a x16 configuration, with single-direction bandwidth of 16GB/s in a x2 configuration, meeting the demands of top-tier SSDs.
In other aspects, PCIe 7.0 will continue to use PAM4 modulation signaling introduced in 6.0, with a 1b/1b encoding scheme, ensuring backward compatibility with all previous PCIe versions.
