Thunderbolt 4 release date

We don't know when exactly to expect Thunderbolt 4 ports in laptops, but nosotros know what to look for. Intel's plans telephone call for Thunderbolt 4 controllers to exist released in 2020, and that the first laptops to feature Thunderbolt 4 volition be those running on Tiger Lake CPUs.
