This is a new development for USB connectivity with USB 4.0 version 2. This should significantly improve bandwidth in particular. Explanations.
As the newspaper reports The edge, USB 4 version 2 could well be the fastest connection available to everyone. Currently, the fastest connection is USB 4 or Thunderbolt version 4, which we still don’t use enough. With these two technologies, speeds currently reach 40 Gbit/s.
USB 4 version 2 to double your bandwidth
Well obviously for this version 2 and still according to The Verge you can reach 80 Gbps thanks to this connection. But the surprising news is that along with literally doubling the speed, it doesn’t even require a cable change. In fact, according to USB-IF, a 40Gbps cable purchased today is capable of exploiting and managing twice the rate, that is, 80Gbps. The USB Implementers Forum (see acronym above) is a non-profit organization formed to promote and support the commercialization of the most popular connectors.
The technical specifications for USB 4 Version 2 are to be published before USB DevDays in Seattle in early November. In any case, we will have to wait a little longer for this connection to be democratized on our products. Especially for our PCs and our smartphones. The press release states that the update “currently aimed specifically at developers“. But it’s true that being able to transfer a 4K Blu-ray in five seconds is quite tempting.
