of USB Promoter Group Announced USB4 version 2.0 A significant upgrade over the original standard. The biggest feature that version 2.0 offers is the doubling of available bandwidth from 40 Gbps to a whopping 80 Gbps.
This leap forward makes USB 4 version 2.0 one of the highest performing connectivity standards on the market. It outperforms all current USB Thunderbolt standards, including Thunderbolt 4, which like USB4 is limited to 40 Gbps.
Version 2.0’s blazingly fast speed is due to the new physical layer architecture added to USB4. As a result, version 2.0 uses the existing 40 Gbps passive cable built into USB4 Type-C and adds the newly defined 80 Gbps USB Type-C active cable to reach the 80 Gbps mark.
The new USB4 version also adds new updates to the display functionality. Includes over 20Gbps bandwidth boost for USB 3.2 data tunneling when using alternate modes such as DisplayPort mode. USB4 version 2.0 has also been updated with the latest versions of the DisplayPort and PCIe specifications.
Of course, like all previous USB versions, USB 4 version 2.0 is backward compatible with previous revisions including the original USB4 standard, USB 3.2, USB 2.0 and Thunderbolt 3.
According to the USB group, version 2.0 was created specifically to benefit users running many different devices over a single USB port, such as docks, high-performance displays, and more. This makes a lot of sense, since version 2.0’s 80 Gbps bandwidth is incredibly excessive for the majority of the population.
However, for power users who regularly power off their laptops from larger setups incorporating multiple DisplayPort monitors, USB drives, Ethernet, etc., 80 Gbps of bandwidth will be useful and allow for better connectivity between these devices. is guaranteed to have no bandwidth limitations. host system.
