PCIe 8.0 Announced With 256 GT/s For AI Workloads

BrianFagioli shares a report from NERDS.xyz: PCI-SIG says PCI Express 8.0 will hit a raw bit rate of 256.0 GT/s, doubling what PCIe 7.0 offers. The spec is expected to be ready by 2028, and the goal is to support massive data loads from AI, machine learning, edge computing, and even quantum systems. The group says PCIe 8.0 will allow up to 1 terabyte per second of bidirectional throughput with a full x16 configuration. They're also looking at new connector designs, improving protocol efficiency, reducing power use, and maintaining backward compatibility.
