"With an expected raw bit rate of 256 gigatransfers per second (GT/s) and up to 1 TB/s bi-directionally across a 16-lane configuration, PCIe 8.0 is set to deliver another doubling of bandwidth over its predecessor, something the engineers weren't sure could be done."
"Micron, for example, announced mass production of what it claims is the first PCIe 6.0 SSD in February this year, four years after the standard was finalized. And with compatible CPUs from Intel and AMD not expected until later this year, there are only PCIe 5.0 systems available to plug them into."
"PCI-SIG says PCIe 8.0 is designed to meet the high-bandwidth, low-latency demands of data-hungry markets, including AI, datacenter infrastructure, high-speed networking, edge computing, and quantum computing."
The PCI Special Interest Group released draft 0.5 of the PCIe 8.0 specification, featuring a raw bit rate of 256 gigatransfers per second and up to 1 TB/s bi-directional bandwidth across 16-lane configuration. This represents a doubling of bandwidth over PCIe 7.0. The complete specification is targeted for 2028 release, though actual hardware availability will likely extend beyond that timeline. PCIe 6.0 SSDs took four years to reach mass production after standard finalization, and compatible CPUs are still pending. PCIe 8.0 is designed for high-bandwidth, low-latency applications including AI, datacenters, high-speed networking, edge computing, and quantum computing. The standard aims to compete with proprietary technologies like Nvidia's NVLink through enhancements such as Unordered I/O introduced in PCIe 6.1.
