As seems to happen every couple of years, a new USB specification has been announced for us to adopt at some point in the future. USB 3.2 Gen 2×2 was announced in 2019 along with the whole renaming thing, and USB4 version 1.0 was announced later that same year. Now, we’ve got the USB4 V2.0 spec, and it’s quick!

The speeds have essentially doubled with each new generation since USB 3.2 Gen 1 (what was originally called USB 3.0). Gen 1 was 5Gbps, Gen 2 is 10Gbps. Gen 2×2 is 20Gbps. USB4 V1 is 40Gbps and now the USB4 V2 specification boasts up to 80Gbps transfer speeds. The USB Promoter Group has also announced that the new standard brings updates to data and display protocols to better utilise that bandwidth, too.

In an effort to keep us permanently confused with the rapid advancement of USB speeds and technology, the USB Implementers Forum (USB-IF) has published the specification for USB4. It was first teased back in March of this year, not long after USB 3 had all its versions renamed. Unlike the incremental updates from USB 3 to USB 3.1 to USB 3.2, though, USB 4 will be a “major update”.
