PCIe 8.0: Double the Speed, Powering AI and Quantum Computing

PCI-SIG announced that the PCIe 8.0 specification, targeting a 2028 release, will boast a raw bit rate of 256 GT/s—double that of PCIe 7.0. This translates to a potential 1 TB/s bidirectional throughput in a full x16 configuration. Designed to handle the massive data demands of AI, machine learning, edge computing, and even quantum systems, PCIe 8.0 also focuses on improved protocol efficiency, reduced power consumption, and backward compatibility. Its applications span high-performance computing, hyperscale data centers, aerospace, and automotive industries.
