Now every bit of information about the Thunderbolt 4 has been officially revealed by the Santa Clara based silicon giant.

What is Thunderbolt 4?

The fourth-generation cable connective solution from Intel promises to deliver improved minimum performance of data transfer on the single cable. The Thunderbolt 4 technology is compliant with USB 4, DisplayPort and PCI Express (PCIe) comes integrated with Intel’s latest Tiger Lake processors.

The new Thunderbolt 4 solution offers 40Gbps data transfer speeds that remains similar to the previous generation.
