USB 4 version 2.0

September 3rd, 2022 by Stephen Jones Leave a reply »

USB 4 version 2.0 is expected to provide twice the speed of data performance over existing USB Type-C cables and connectors. The new technology, will launch later in 2022, and should deliver greatly improved connectivity and data transfer speeds. The advances, are made possible by a new physical layer architecture allowing up to 80GBps operation – even when using previousĀ USB C passive cables, which previously allowed up to 40GBps speeds.

his means that a 40GBps cable bought today would soon be able to deliver double these speeds, with no extra effort required by the user. 

Existing USB-C and USB Power Deliver (PD) specifications will be updated to enable the new levels of performance, with the protocols backwards-compatible with USB 4 version 1.0, USB 3.2, USB 2.0 and Thunderbolt 3. There’s also improved support for DisplayPort and PCIe, where improved data tunnelling will be used to harness the best possible bandwidth.

Solutions will most benefit from this speed enhancement include: higher-performance displays, storage, and USB-based hubs and docks.

More information, together with detailed technical specifications into how USB 4 version 2.0 will work, are expected to be revealed in November 2022.
