As the most common port specification, USB is unexpectedly confusing in naming, especially in the era of USB 3.0, with the introduction of USB 3.1 and USB 3.2, the previous specifications will also be renamed (such as USB 3.0). It was first changed to USB 3.1 Gen 1, and later changed to USB 3.2 Gen 1, which is actually the same thing), causing a lot of confusion among consumers. Originally, the launch of USB 4 also meant to consolidate the chaos on the market in a large way, and reverted to a single naming, but now it seems that the old habit is revived once more.
The driving force behind the USB specification USB Promoter Group Announced that the next-generation USB specification is coming soon, and named USB 4 Version 2.0. The new specification will increase the maximum transfer rate from 40Gbps to 80Gbps, and both the existing 40Gbps USB Type-C passive cable and the upcoming 80Gbps Type-C active cable have the potential to achieve such high speeds. This means that if you are using a 40Gbps USB 4 cable now, you will not need to buy a new cable for future upgrades.
It’s unclear when USB 4 Version 2.0 will come to consumer devices. In the press release, the USB Promoter Group stated that the current update is still “developer testing.”
