On June 11, 2025, PCI-SIG officially announced the release of the final PCI Express 7.0 specification, marking a new era in high-speed computer system connectivity. This long-awaited standard represents a significant leap forward in data transfer technology development.
PCIe 7.0 Technical Specifications
The new PCIe 7.0 standard doubles performance compared to its predecessor, achieving an impressive data transfer rate of 128 GT/s (gigatransfers per second). In practical application, this means devices using the maximum 16-lane configuration (x16) can achieve bidirectional bandwidth of up to 512 gigabytes per second.
Key technical features of PCIe 7.0 include:
- Data transfer rate: 128 GT/s per lane
- Bandwidth: up to 512 GB/s bidirectional (x16)
- Signaling: PAM4 (Pulse Amplitude Modulation with 4 levels)
- Power efficiency: improved power management
- Compatibility: backward compatibility with previous PCIe generations
Applications
PCIe 7.0 opens new possibilities across various application domains. Next-generation graphics cards will be able to process even more complex visual effects and support 8K and higher resolution gaming. Servers and data storage systems will gain the ability to process large volumes of information with minimal latency.
PCIe 7.0 becomes particularly important in artificial intelligence and machine learning applications, where rapid transfer of large datasets between processors and specialized accelerators is required.
PCIe 8.0 Development Plans
PCI-SIG has already announced the beginning of the PCIe 8.0 research phase, which should provide bandwidth up to 1 TB/s. This demonstrates continuous standard development and readiness for future high-speed data transfer needs.
Implementation Timeline
While the specification is ready, the first commercial products with PCIe 7.0 support are not expected before 2027-2028. This is due to the need to develop appropriate controllers, adapt manufacturing processes, and ensure compatibility with existing systems.
