Intel unveiled its protocol specifications while integrating Thunderbolt 3 support, a high-speed data transfer technology developed by the company in 2017, into the CPU. And will offer royalty-free services to other companies. While Thunderbolt 3 declared royalty-free, other makers of Thunderbolt 3 became compatible with Thunderbolt 3, resulting in USB 4.

The USB 4 terminal has the same shape as USB Type C, and is compatible with USB 2.0, 3.2, and Thunderbolt 3. Encoding uses a 128b / 132b certified cable and the maximum transmission speed is 40Gbps. The DisplayPort and USB Power Specification will also be supported.
