A new USB technology improvement standard is on its way. It is called USB4 and it was announced on the 31st of January 2020. It seems to be part of the existing USB Type-C standard. So, the connector itself will not change.
The USB4 architecture is based on the Thunderbolt technology that Apple uses on their computers. The Thunderbolt protocol specification is recently contributed by Intel Corporation to the USB Promoter Group the press release says. It doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols.
It seems like they are looking for areas to increase the speed this time
Key characteristics of the USB4 solution will include these improvements
- Two-lane operation using existing USB Type-C cables and up to 40Gbps operation over 40Gbps certified cables
- Multiple data and display protocols that efficiently share the maximum aggregate bandwidth
- Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3
This sounds great. Another thing I like about USB standard is as mentioned above here about backward compatibility with USB 2.0, USB 3.2 or even Thunderbolt 3. It is great to see the value that any USB user will have by buying USB4 compatible mem sticks or another USB device. This means that older computers with USB 2.0 will be able to read USB4 devices which is very handy.
The non-profit USB Implementers Forum, Inc. was formed to provide a support organization and forum for the advancement and adoption of USB technology as defined in the USB specifications. Further information, including postings of the most recent product and technology announcements, is available by visiting the USB-IF website at www.usb.org
We saw that the news on www.usb.org was posted in a PDF document. So we decided to create an article explaining it all for you.
What do you think of USB4?
