Intel has introduced a new Thunderbolt 4 interface with support for 8K displays

Intel introduced the fourth generation of the wired Thunderbolt interface. Despite the speed identical to its predecessor, the new revision received a number of useful innovations, including support for new-generation monitors, a large cable length, and increased charging power for laptops. 

Thunderbolt 4 has a maximum data transfer rate of 40 Gb/s via USB Type-C 4.0, which supports backward compatibility with the previous standard. Among the key changes that affected the new interface are the possibility of using universal cables up to two meters long, as well as support for hubs equipped with four Thunderbolt 4 ports.

When connected via PCIe, the new interface provides transfer speeds of up to 32 Gbit/s - twice as high as that of the previous standard. It is possible to connect two 4K displays or one with a resolution of 8K. When using Thunderbolt 4 to power connected devices, the maximum power available is 100 watts. 

The first processors to receive support for the new interface will be Intel's Tiger Lake mobile chips.
