### Press Release:
PCI-SIG today announced that the PCI Express (PCIe) 8.0 specification will double the data rates of the PCIe 7.0 specification to 256.0 GT/s, with plans for release to members by 2028.
#### Feature Objectives:
– Delivering 256.0 GT/s raw bit rate and up to 1 TB/s bi-directionally via x16 configuration.
– Reviewing new connector technology.
– Confirming latency and Forward Error Correction (FEC) targets will be achieved.
– Ensuring reliability targets are met.
– Maintaining backward compatibility with previous generations of PCIe technology.
– Developing protocol enhancements to improve bandwidth.
– Continuously emphasizing techniques to reduce power.
### Future Applications:
The PCIe 8.0 specification is aimed at supporting emerging applications like Artificial Intelligence/Machine Learning, high-speed networking, Edge computing, and Quantum computing; as well as data-intensive markets such as automotive, hyperscale data centers, High-Performance Computing (HPC), and military/aerospace.
“Following this year’s release of the PCIe 7.0 specification, PCI-SIG is excited to announce that the PCIe 8.0 specification will double the data rate to 256 GT/s, maintaining our tradition of doubling bandwidth every three years to support next-generation applications,” said Al Yanes, PCI-SIG President and Chairperson. “With the increasing data throughput required in AI and other applications, there remains a strong demand for high performance. PCIe technology will continue to deliver a cost-effective, high-bandwidth, and low latency I/O interconnect to meet industry needs.”
“As artificial intelligence and other data-intensive applications continue to scale rapidly, PCIe technology demand will be sustained in the long run due to its high bandwidth, scalability, and power efficiency,” said Reece Hayden, Principal Analyst at ABI Research. “Data center networks are already preparing to implement PCIe 6.0 technology and are showing great interest in the PCIe 7.0 specification. The introduction of the PCIe 8.0 specification further ensures that the industry’s bandwidth requirements will be supported well into the future.”
