Thank you CTOnews.com netizen Hello ah_rabbit clue delivery! CTOnews.com June 14 news, PCIe 5.0 SSD is currently in large-scale listing, PCIe 6.0 is not yet commercial. PCIe 7.0 is also on the way, according to the latest news from the PCI-SIG standards development group.

PCI-SIG has finalized the draft of PCIe Gen7 (PCIe 7.0) v0.3 version. According to the design, its bandwidth is doubled again compared with PCIe 6.0, and the speed is increased from 64 GT/s to 128 GT/s. It also adopts PAM4 modulation signaling, and the encoding mode is 1b / 1b, which is backward compatible with all previous PCIe versions.

▲ According to the formula of GT/s conversion GB/s, the PCIe 7.0 bidirectional transmission rate of x16 can reach 128*1/8*16*2 to 512 GB/s.

However, none of this information is new, it was published last year. 0.3 The details contained in the PCIe 7.0 specification are not yet public, so we do not know the exact implementation details for PCIe 7.0. Foreign media AnandTech pointed out that PCIe 7.0 has identified the core technology foundation, and the follow-up work is to continuously optimize.

▲ Pixabay can be seen from another PPT that the target release time of version 1.0 of PCIe 7.0 is 2025, and it will take longer until CTOnews.com is actually used. PCIe 5.0, for example, was launched as early as version 1.0 in 2019, but until now most ordinary users have not used it.
