USB 4 - New name for Thunderbolt 3

Thunderbolt 3, the USB-C interface with transfer protocols from Intel, will be called USB 4 in the future. After seeing you guys yesterday Confusion around USB 3.2 I would like to say a few words about this today. Because the protocol specification of Thunderbolt 3 was handed over by Intel to the USB Implementers Forum (USB-IF). Once the standardization of USB4 standards has been completed, manufacturers will in future be able to offer corresponding connections, cables, devices and other products without having to buy licenses from Intel. So we can look forward to articles with up to 40 Gbit / s and many parallel uses.

Thunderbolt 3 will become the USB 2019 or USB4 standard in 4. 40 GBit / s as well as parallel data and display protocols are then possible via USB.

Information on USB 4 or USB4

In einer press release all details of the current process were made available to the public. It states that the USB4 architecture should be based on the Thunderbolt protocol, which was contributed by Intel Corporation. This doubles the current bandwidth of USB and makes it possible to use several data and display protocols at the same time. The downward compatible standard (compatible with USB 3.2, USB 2.0 and Thunderbolt 3) should enable a data rate of up to 40 Gbit / s with appropriately certified cables. The whole thing runs on the current USB-C type. It is interesting that in the new standard the space is left out and USB4 is apparently written together.

Publication planned for mid-2019

"With over 50 companies actively involved in reviewing the final draft specifications, the USB4 specification is on its way to being released in mid-2019“, It says (translated) in the press release linked above from the Universal Serial Bus Implementers Forum (USB-IF) and the USB Promoter Group. This will of course also be accompanied by adapted USB-C specifications. According to hot online should solve the docking problem for notebooks and tablets with USB 4 / USB4. Because DisplayPort and USB capabilities would then possibly no longer be tapped and allocated individually, but made usable at the same time. So interesting prospects.
