We are facing the new generation of USB cables and inputs, USB 4 version 2, which promises a much faster connection. Currently, the original USB 4 or Thunderbolt 4, the latest connectors that we currently have on the market, offer a speed of 40Gbps. Now version 2 promises double speed i.e. 80Gbps.
Our friends at The Verge reveal that the actual technical specification of the new USB Implementers Forum, which is in charge of the standard itself, has not yet been published, but details about it are still few. The group released a statement where they report that USB 4 version 2 cables will belong to the USB-C standard. This of course comes as no surprise, but the real bombshell is “Key features of the updated USB4 solution include: Up to 80 Gbps operation, based on a new physical layer architecture, using existing passive 40 Gbps USB Type-C cables and Newly Defined 80Gbps USB Type-C Active Cables.”
Now, the advantage that the new charger will have is that you will be able to use the same cable that you currently use and get the same benefit in terms of the speed in which the files will be sent, the load, etc. Joe Balich, a spokesman for USB-IF, did not explain how this is possible, but argued that “this benefit became a requirement when the new specification was developed and details on how 80Gbps signaling is achieved will be released once the new specification is developed.” until the final specification is published.

According to the USB Promoter Group, which is made up of companies like Intel, Apple, Microsoft, HP, and Texas Instruments, the USB-C and power delivery specifications will be updated to “allow for this higher level of data throughput.” USB 4 version 2 will also include new updates that will provide better speeds when using USB 3.2.
Apparently, the new milestone of USB chargers will be presented in the first 15 days of September, but we still do not have a confirmed date. The press release argues that the update is “specifically aimed at developers at this time.” Said like this, they comment that the final guides for brands and marketing will be published later.
