The PCI-SIG today held a briefing around PCIe 8.0 that follows the PCIe 7.0 specification that was released to members last June.
While PCIe 7.0 allows for 512 GB/s bi-directionally in an x16 configuration, PCIe 8.0 will once agian double that bandwidth. PCIe 8.0 will deliver a 256 GT/s raw bit-rate and up to 1.0 TB/s bi-directionally in an x16 configuration. Each PCIe major revision continues to double the maximum data rate.
Like PCIe 6.0 and PCIe 7.0, PCIe 8.0 will continue with PAM4 signalling. Interestingly, the PCI-SIG with PCIe 8.0 is evaluarting new connector technology but they do aim to maintain backwards compatibility with prior generations of PCIe.
PCIe 8.0 also hopes to further reduce power consumption through new techniques. Those are the quick takeaways from today's PCI-SIG media briefing with the PCIe 8.0 draft v0.5 specification release.
