Thunderbolt v4
— the version of this interface is presented in the summer of 2022. Like the third version, it uses USB C connector. Formally, the maximum bandwidth remains the same as its predecessor - 40 Gb / s; however, number of improvements have significantly increased the actual connectivity. So, Thunderbolt v4 allows you to broadcast signal simultaneously to two 4K monitors (at least) and provides data transfer rate according to the PCI-E standard of at least 32 Gb / s (against 16 Gb / s in the previous version). In addition, this interface is mutually compatible with USB4 by default, and the daisy chain function is supplemented by the ability to connect hubs with up to 4 Thunderbolt v4 ports. Other features include protection against DMA (direct memory access) attacks.
