The next generation "USB4" architecture is coming soon
USB-IF announced that the next generation of "USB4" architecture is coming in March this year.
The biggest change is that it will be based directly on the Thunderbolt 3 agreement provided by Intel.
Let's first talk about Thunderbolt, which was jointly developed by Intel 2011 and Apple.
The Thunderbolt protocol supports a variety of physical connectors, initially using the Mini DisplayPort terminal and now with Type-C terminals.
The existing Thunderbolt 3 transmission speed can reach 40 Gbps. In contrast, the existing USB 3.2 transmission speed is 20 Gbps.
Two years ago, Intel opened the Thunderbolt standard to other chip vendors. The USB-IF Forum also took the opportunity to develop a compatible USB4 transmission standard specification with the same transmission technology and 40Gbps speed. In this way, Intel can be regarded as promote Thunderbolt 3 directly.
I thought the USB 3.2 just released!What's different with USB4 ?
It's really can't believe!
Three major features of USB4:
1. Use the Type C cable for dual-channel operation for up to 40Gbps.
2. A variety of data and display agreements to jointly utilize the overall bandwidth.
3. Compatible with USB3.2, USB2.0 and Thunderbolt 3.
USB4's transfer rate is twice as high as USB 3.2's peak, reaching 40Gbps, and is compatible with Thunderbolt 3. These two points are far ahead of USB3.2.
