USB-IF Publishes USB4 2.0, Doubling Bandwidth Over USB-C

The USB Implementers Forum (USB-IF) announced the USB4 2.0 specification, enabling 80 Gbps performance over the USB Type-C cable and connector. The updated spec doubles the USB maximum aggregate bandwidth, which will benefit high-performance displays, storage and USB-based hubs and docks. USB Type-C and USB Power Delivery specs have also been updated to support the higher data performance, the organization said. Guidelines for identifying certified USB 80 Gbps solutions and cables will follow USB-IF’s new unified branding and marketing program, it said, reminding members, “USB specification names and technical terminology are not intended for use when describing USB capabilities to end consumers.”
