Last week during MWC 2019 a new USB standard was announced. The method of wired communication marked with the number 3.2 according to the announcement is to offer a transmission of up to 20GB / s, will appear on the market later this year. As it turns out, this is not the latest standard. Intel announced USB4. According to the manufacturer, this standard will ensure transmission twice as fast as 3.2 – up to 40GB / s – as well as integration with Thunderbolt 3.
Intel decided to make Thunderbolt 3 available to other manufacturers (open license), and USB4 will be integrated with this technology. So it turns out that the new standard will become the successor of both USB and Thunderbolt, winning the title of king of wired communication. This is good information, because USB connectors are and will be much more common than Thunderbolt connectors – so far only 463 devices using the second communication method have been certified.
Unfortunately, apart from this information, we will not learn much more. USB Promoter Group does not intend to share detailed specifications until about the middle of this year. There is no mention of USB4 compatibility with future versions of Thunderbolt, but Intel claims that it is still going to support and promote this second solution.
Details about USB4 will appear most probably during the Computex Taipei 2019, which will take place at the turn of May and June.
