The data protocol brings support for USB 3.2 data tunneling for speeds up to 20 Gbps. There is also support for advanced DisplayPort and PCIe specifications. Additionally, USB 4 version 2.0 comes with support for USB4 version 1.0, USB 3.2, USB 2.0 and Thunderbolt 3.
The USB Promoter Group, which includes Apple, Microsoft, Intel, and more, has also confirmed an upcoming update of the USB Type-C and USB Power Delivery (USB PD) specifications and has scheduled USB DevDays developer events in November.
In addition, USB 3.2, DisplayPort, and PCI Express (PCIe) data tunneling are lined up for major updates.
How does USB4 differ from USB-C?
You can think of USB Type-C (or USB Type-A, etc.) as the physical size of ports and plugs, and USB 4 (or USB 3.2, Thunderbolt 4, etc.) as the underlying technology. All USB4 products use the USB-C connector, but not all USB-C cables and ports use the USB4 protocol.
USB4 is the latest generation of USB, maintained by the USB Implementers Forum (USB-IF). The USB4 architecture and previous generations of USB, such as USB 3.2 and 2.0, refer to a host computer or cable bus supporting data exchange between devices and peripherals, as USB-IF puts it in the USB4 specification.
We expect to get more details about USB 4 2.0 and USB Type-C, and USB PD specifications during USB Developer Day 2022. The event will be held in Seattle/WA on November 1-2 and Seoul/South Korea on November 15-16. It remains to be seen when this standard will be commercially available!
