In the coming months, several new devices will be launched that already enable USB 4.0. This is especially true for the connection of screens. New data and display protocols are also supported, enabling a wider range of connectable devices, better transmission rates and increased power supply to external devices. However, new plugs are not needed, it remains with USB-C connectors. This makes USB 4.0 twice as fast as its predecessor.
Data transfers of at least 20 Gbit/s and up to 40 Gbit/s are guaranteed. Therefore, USB 4.0 can confidently be called a revolution. This technology was previously reserved for expensive devices. USB 4.0 is based on the specifications of the Thunderbolt 3 protocol, which was jointly developed by Apple and Intel. With this, significant improvements in terms of speed and amount of electricity were also achieved. It was the birth of the USB Type C connector. New cables and connectors had to be purchased. Since USB 3.0 and its successor generations came on the market in 2019, it was easy to lose track, as the plugs of this generation all looked identical. Already presented in 2019, USB 4.0 or USB 4 should simplify the confusing variety of different specifications.
