The USB Promoter Group has recently announced its new USB4 2.0 standard which has made the USB naming criteria even harder. The official press release stated that the new USB4 2.0 standard will bring faster speeds to USB cables.
It will offer transfer speeds of up to 80 Gbps, almost twice more than the transfer speeds on USB Type-c Thunderbolt 4. Moreover, it allows increased compatibility with USb4 capable and will also support active Type-C cables with speeds up to 80 Gbps.
“Once again following USB tradition, this updated USB4 specification doubles data performance to deliver higher levels of functionality to the USB Type-C ecosystem,” said Brad Saunders, USB Promoter Group Chairman. “Solutions seeing the most benefit from this speed enhancement include higher-performance displays, storage, and USB-based hubs and docks.”
When it comes to naming, the USB criteria have always been a headache. There are categories with sub-categories and even further iterations and now the same will be true for USB4 which already has a second variation.
