What changes can USB4 bring to our applications?

Last Update Time: 2020-10-10 10:40:56

Everyone is no stranger to the USB interface. This is the most frequently used and most common interface for computers.

USB-IF released the USB 4 specification as early as September of this year, but this specification has not yet appeared on any device, and everyone is still relatively unfamiliar with it (there will be a device listed next year as soon as possible). On the basis of USB 3.0, USB 4 has undergone major changes in transmission speed and interface form. Let ’s take a look at the improvements and use USB 4 to achieve what previous generations could not do!

Thunderbolt is a product co-developed by Intel and Apple, so it is a matter of designing patents. However, this year Intel provided Thunderbolt 3 to the USB Promoter Group for free, making the technology available in USB4. Because of this, the maximum speed of USB4 is upgraded from 20Gbps of USB3.2 to 40Gbps.

USB4 will support a maximum of 100W power supply, which will solve the problem of excessive power supply and insufficient power for external devices. There will no longer be a problem that the USB multi-port connected mobile hard disk cannot be used. The USB4 interface type has selected the current mainstream USB-C (Type-C) interface, and multi-use has become a reality. (Although USB4 is upwardly compatible with USB3.0, the change in the interface mode has resulted in the inability of USB3.0 interface devices to directly use the interface Conversion).

USB4 has made changes in three points: data transmission speed, power supply, and interface form. The emergence of the USB4 interface is bound to break some of the limitations of current external devices, making the computer more scalable.

Whether it's a desktop computer or a laptop, simple design will be the mainstream in the future. One of the factors currently affecting the appearance of notebooks is the problem of excessive openings. USB4 just solves this pain point. Data transmission speed and power supply make the multi-use one a reality, which will undoubtedly help the appearance and thickness of the notebook.

Through the USB4 interface, a variety of expansion devices such as monitors, sound cards, and graphics cards can be connected. The main issue here is the external graphics card. The external graphics card is the best solution to the notebook gaming problem (notebook portability and gameplay will not be affected). Although the USB 3.0 era already has a solution for external graphics cards, but it is limited to the limitation of data transmission bandwidth, causing some high-end graphics cards to only play less than 50% of the performance. The emergence of USB4 will break this bottleneck or indirectly promote external Development of graphics cards.
