USB Promoter Group, the group of companies responsible for USB standardization, this week announced version 2.0 of USB 4, hitting an incredible 80 Gbps. The number is double promised, with a maximum of 40 Gbps achieved by Intel’s Thunderbolt 4.
Version 2.0 of USB 4 will run through the USB-C connector, which is the most modern form currently used in most mobile phones and commonly seen in newer laptops. It is backwards compatible with versions of USB up to 2.0, but not USB 1, which is the first generation of the technology and is more than 25 years old.
It’s worth noting that USB 4 version 2.0 supports Thunderbolt 3, but not Thunderbolt 4. That could change in the future if Intel adapts the current generation of its technology to the recently announced USB standard. It is interesting to note that the first version of USB 4 is almost equivalent to Thunderbolt 3 and 4, and the connections can be used freely in terms of support and compatibility.
With the new version of USB 4, it will become more important to evaluate the type of cable purchased in addition to the connection. After all, only newer cable models properly prepared for version 2.0 will be able to reach speeds of 80 Gbps.
