USB 4 Version 2.0 Announced: Features Up to 80Gbps Transfer Speed
The USB Promoter Group has announced its next USB version upgrade, which is USB 4 version 2.0. This is expected to support a data transfer speed of up to 80Gbps over the USB Type-C cable and connector. So check out all you need to know about this new development.
In a press release made by Intel, HP, Microsoft, Renesas Electronics, STMicroelectronics, and Texas Instruments Apple which are known as the USB Promoter Group, they announced that the USB 4 version 2.0 will allow users to transfer media/files/documents e.t.c with a speed of up to 80Gbps using the USB Type-C cable and connector.
Though we should be expecting further details on the USB Developer Days 2022 event in November, the USB Promotor Group also confirms that the USB Type-C and USB Power Delivery (USB PD) specifications will also be updated to reach the claimed performance. Furthermore, the USB 4 Version 2.0 will also support backward compatibility for the previous USB 4 version.
Other details we know about the USB 4 version 2.0 is that it is based on a new physical layer architecture that uses the existing 40Gbps USB Type-C passive cables and 'newly-defined' USB Type-C active cables. The USB Promotor Group is also working on a protocol update that allows the USB 3.2 data tunneling to exceed the speed of 20Gbps to be compatible with the latest versions of DisplayPort and PCIe data tunneling.
More on compatibility, we should be expecting the USB 4 Version 1.0, USB 3.2, USB 2.0, and ThunderBolt 3 to be compatible with the USB 4 version 2.0. As said earlier, more details on the specifications and compatibility are expected to be shared ahead of the USB Developer Days 2022 event in November this year.
