The PCI-SIG Builders Convention 2022 is in full swing, and at present the requirements committee behind the ever-present PCIe interface introduced that the PCIe 7.0 specification is focused for launch to its members in 2025 with a knowledge price as much as 128 GT/s (earlier than encoding overhead). That can equate to 512 GB/s of bi-directional throughput through a 16-lane (x16) connection. As a reminder, the PCI-SIG is the consortium behind the PCIe interface, which is an open trade commonplace that includes over 900 member corporations.

The PCI-SIG notes that the PCIe 7.0 interface will present a blistering 512 GB/s of bi-directional throughput over a x16 connection, however that’s earlier than encoding overhead and the impression of header effectivity. The 7.0 interface will proceed to make use of the PAM4 encoding tech that was launched with PCIe 6.0. As such, the real-world usable bandwidth will likely be considerably decrease, however nonetheless signify a doubling over the PCIe 6.0 interface.
