PCIe 7.0 spec nearing completion, promising 16GB/s per lane bandwidth
PCIe 7.0 aims to provide 16GB/s per lane, doubling bandwidth for AI and machine learning.

The PCI Special Interest Group (PCI-SIG) is nearing the finalization of the PCIe 7.0 specification, anticipated to offer an impressive 16GB/s per lane. This development is significant as it doubles the bandwidth when compared to the previous PCIe 5.0, which provided 4GB/s per lane.
The growing demands of AI and machine learning have underscored the necessity for this increased throughput. Revision 0.7 of the draft specifications has been released with minimal changes, suggesting that the core technology is stable and could be ratified by the end of 2025.
One major challenge accompanying this increased bandwidth is the consequential heat generation, necessitating new cooling solutions. While PCIe 7.0 promises high-speed data handling, real-world product availability might take time due to extensive testing and cooling innovations.
