PCIe 7.0 standard draft announced, next-generation interface speed doubled!

News on June 14, according to the latest news, PCI-SIG (Peripheral Component Interconnect Special Interest Group) development group has finalized the draft of PCIe Gen7 (PCIe 7.0) v0.3 version, which marks the PCIe The research and development work of 7.0 is progressing steadily. PCIe 7.0, as the next generation PCI Express interface standard, is expected to be commercialized in the next few years.

According to the PCI-SIG plan, PCIe 7.0 will once again break through the bandwidth limit, and its transmission rate will double from the existing 64 GT/s of PCIe 6.0 to 128 GT/s. with PCIe Same as 6.0, PCIe 7.0 uses PAM4 modulation signaling and 1b/1b encoding mode, and is backward compatible with all previous PCIe versions.

It is understood that the detailed implementation details of PCIe 7.0 have not been made public, and currently only the draft version 0.3 specification is available for reference. However, foreign media AnandTech pointed out that PCIe 7.0 has determined the core technology foundation, and future work will focus on continuous optimization and improvement.

The first version of PCIe 7.0 is expected to be released in 2025. However, despite PCIe The first version of 5.0 was released in 2019, but until now, most ordinary users have not used this version of the PCIe interface. Therefore, although PCIe The release time of 7.0 has been determined, but it will take quite a long time before ordinary users can actually use this interface.

The above is the detailed content of PCIe 7.0 standard draft announced, next-generation interface speed doubled!. For more information, please follow other related articles on the PHP Chinese website!
