USB 4 Version 2.0 Announced with Expected 80Gbps Speed

USB 4 Version 2.0 Announced with 80Gbps Speed

The next-generation USB 4 Version 2.0 features are now available with the help of the USB Promoter Group. Data transfer speeds will significantly increase with the introduction of USB 4 Version 2.0, doubling them to 80 Gbps using a USB Type-C cable and connector. Here are some further details.

USB 4 Version 2.0 Specifications Announced

By using 40 Gbps passive Type-C cables and 80 Gbps Type-C active cables, a new physical layer architecture will be used to accomplish the 80 Gbps data transfer speeds. Additionally, it will support more recent data and display standards, and the available bandwidth has increased.

Support for USB 3.2 data tunneling at speeds of up to 20 Gbps is provided via the data protocol. Additionally, the updated DisplayPort and PCIe requirements are supported. Support for USB 4 Version 1.0, USB 3.2, USB 2.0, and Thunderbolt 3 is also included in USB 4 Version 2.0.

"Once again following USB tradition, this new USB4 specification doubles data performance to bring higher levels of functionality to the USB Type-C ecosystem," said Brad Saunders, chairman of the USB Promoter Group.

Higher-performance screens, storage, and USB-based hubs and ports are the solutions benefiting the most from this speed improvement.

The USB Promoter Group, which is made up of companies like Apple, Microsoft, Intel, and others, has also stated that it would update the USB Type-C and USB Power Delivery (USB PD) specifications soon. This will take place before the November USB DevDays developer gatherings.

Additionally, significant upgrades are coming for DisplayPort, PCI Express (PCIe) data tunneling, and USB 3.2.

During the USB Developer Days in 2022, we expect to learn additional features of the USB-4 2.0, USB Type-C, and USB PD specifications. The event will take place in Seattle, Washington, on November 1-2, and Seoul, South Korea, on November 15–16. When this standard will be marketed is still up in the air!
