USB 4.0

“Speed freaks will be happy”

“The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution,” said USB Promoter Group Chairman Brad Saunders in a statement. 

“The USB4 solution specifically tailors bus operation to further enhance this [by] enabling the further doubling of performance.”

“Yep, double the performance (40Gbps) compared with the fastest version of USB 3.x which offered 20Gbps. However, there is a bit of a sour note because that’s exactly the same speed as Thunderbolt 3, meaning that there will be no enhancement for current Thunderbolt 3 devotees on a standard that will be several years old already. “

“Existing USB Type-C cables will be able to transfer through two lanes, whereas if you have compatible certified cables, you’ll be able to transfer up to 40 Gbps.”

The Connector

“The USB-C connector was designed to be future proof and reversible. It will be staying. The new standard will be backward compatible with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts although if they don’t have USB-C connectors they will, naturally, need an adapter. “
