Thunderbolt™ 4 and its features

Intel officially released the specification of Thunderbolt™ 4 in 2020, integrating various technologies into an all-in-one high speed interface.

Thunderbolt™ 4 can reach up to 40Gbps in data rate, which is the same as its predecessor Thunderbolt 3. However, the two generations vary greatly in the physical layer. Additionally, Thunderbolt™ 4 is compatible with USB4™. The following table shows different features of USB3.2 Gen2, USB4 Gen3, Thunderbolt 3, and Thunderbolt 4.
