Intel has introduced a Thunderbolt 3 hub at IDF 2015. Thunderbolt 3 is Intel’s own connector that can achieve quadruple bandwidth compared to UBS Type-C.
The Thunderbolt hub can beef up laptop graphics, charge the laptop, drive two 4k displays and act as a USB hub at the same time over one single Thunderbolt 3 cable. The hub has three USB 2.0, one Type-C, two HDMI and two DisplayPort connectors and it can power all those at the same time except the additional displays are limited to two 4k displays.
At the demo hub there’s just an AMD R9 M385 but it’ll most likely be capable to handle full desktop GPUs. The possibilities this could bring to gamers are great. The same very portable laptop used in work or school would be able to run the greatest PC games.
The Intel’s solution will not be available for consumers but other manufacturers can build their own Thunderbolt hubs. MSI has build something like this previously with their GS30 but it needed a full PCIe connector to work which made it a little clumsy.
