USB4 Version 2.0 coming soon
The USB4 standard is also preparing to be updated, passing to version 2.0 which will double the available bandwidth, passing from the current 40Gb / s to the future 80Gb / s. The announcement, which will make the connection superior to the current USB Thunderbolt standards (Thunderbolt 4 is limited to 40Gb / s as well as USB4) was recently made by the USB Promoter Group and, to achieve this incredible speed, it was necessary to upgrade the level. physical architecture.
As for the rest of the news, we find an increase in bandwidth beyond 20Gb / s for USB 3.2 data tunneling when using alt modes such as DisplayPort. In addition, all updates related to the latest versions of the Display Port standard and PCIe specification have been included. As always, of course, full compatibility is also maintained with previous USB standards, such as USB4 Version 1.0, USB 3.2, USB 2.0 and Thunderbolt 3. Surely, such a high bandwidth will be useful for those who use advanced docks for connection. of various peripherals (such as monitors, accessories and more), so as to pass all the data through a single cable.
Some users have been quite baffled about using the USB Version 2.0 nomenclature instead of a direct pass to USB5 to define the new standard. As noted by the user @ghost_motley on Twitter, so far the choice of names to be associated with each update of the USB standard has not been particularly happy.

On the occasion of the USB Developer Days 2022 events, which will be held in Seattle, USA, and Seoul, South Korea, further technical details and the latest updates regarding the USB4, USB Type-C and USB PD.
USB 4 Version 2.0 Details Announced; Expect up to 80 Gbps Speeds
The next-gen USB 4 Version 2.0 specifications are now out, courtesy of the USB Promoter Group. It is revealed that the USB 4 Version 2.o will bring along a major upgrade to the data transfer speeds, doubling it to 80 Gbps over USB Type-C cable and connector. Here are more details to know.
The 80 Gbps data transfer speeds will be achieved by a new physical layer architecture with the use of 40 Gbps passive Type-C cables and 80 Gbps Type-C active cables. It will also support updated data and display protocols and there’s an increase in the available bandwidth.
The data protocol brings support for USB 3.2 data tunneling for speed up to 20 Gbps. There’s also support for the upgraded 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.
Brad Saunders, USB Promoter Group Chairman, said, “Once again following USB tradition, this updated USB4 specification doubles data performance to deliver higher levels of functionality to the USB Type-C ecosystem. Solutions seeing the most benefit from this speed enhancement include higher-performance displays, storage, and USB-based hubs and docks.“
The USB Promoter Group, which includes Apple, Microsoft, Intel, and more, has also confirmed to update the specifications of the USB Type-C and USB Power Delivery (USB PD) soon and this shall happen prior to the USB DevDays developer events scheduled for November.
In addition, USB 3.2, DisplayPort, and PCI Express (PCIe) data tunneling are in line for major updates.
We expect to get more details on the USB 4 2.0 and USB Type-C, and USB PD specifications during the USB Developer Days 2022. The event will take place on November 1-2 in Seattle/WA and November 15-16 in Seoul/South Korea. It remains to be seen when this standard will be commercially available!
