Welcome to the next generation of USB performance. Today’s advanced devices require significantly higher data performance to maintain the interactive experiences users have come to expect. USB4™ represents a major update to deliver the next generation of USB architecture – enabling the highest USB bandwidth available and extending
USB Type-C® performance.

The USB4 Specification complements and builds upon the existing USB 3.2 and 2.0 architectures. Based on the Thunderbolt™ protocol specification contributed by the Intel Corporation, USB4 doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols.

The USB4 architecture defines a method to dynamically share a single high-speed link with multiple end device types to best serve the transfer of data by type and application. As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host the ability to optimally scale allocations for display data flow. Compatibility with existing USB 3.2, USB 2.0, and Thunderbolt 3 hosts and devices is supported, and the resulting connection scales to the best mutual capability of the devices being connected.  

Key characteristics of the USB4 solution include:

  • Two-lane operation using existing USB Type-C cables and up to 40 Gbps operation over 40 Gbps certified cables

  • Multiple data and display protocols to efficiently share the maximum aggregate bandwidth over the bus

  • Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3
