Buy a USB4.0 data cable, the transmission rate is very fast.
Specifically, USB 4 has the following three main features:
First, the USB 4 specification will introduce dual-link channels;
Second, The transmission bandwidth reaches the 40Gbps standard of Thunderbolt 3;
Third, its physical layer form is TYPE-C.
Based on the above three characteristics, USB 4 integrates the advanced technology of Thunderbolt 3 and directly has the data transmission capability of ultra-large bandwidth, direct display input/output function, and charging function. It can be said that a full-featured USB 4 interface is currently the most versatile, smallest, and fastest physical interface!
In addition, USB 4 has also made comprehensive considerations in terms of compatibility. It is directly backward compatible with USB 3.2, 3.1, 3.0, and 2.0, and is also compatible with Thunderbolt 3. The current standard USB data All cables can be used on USB 4.
In terms of naming, the USB Promoter Group may no longer use version iterative naming methods such as 3.0, 3.1, and 3.2. USB 4 may always use the USB 4 naming method. At the same time, its physical form will only be TYPE-C. Therefore, in the future, USB interfaces of electronic devices and related external expansion devices will uniformly adopt the compact TYPE-C form, which will promote the development of laptops, tablets and other devices to become thinner and lighter.
·Why is USB 4 worth looking forward to?
The performance leap of the USB 4 interface is mainly due to Thunderbolt 3.
Thunderbolt is what we know as the Thunderbolt interface. In 2011, Thunderbolt, developed jointly by Intel and Apple and codenamed "Light Peak", was officially announced. It is what we call the Thunderbolt interface, and Apple's official website calls it the "Thunderbolt" interface (hereinafter collectively referred to as the Thunderbolt interface).
Since the Thunderbolt interface combines two communication protocols, PCIE and DisplayPort, before the advent of the full-featured TYPE-C, the Thunderbolt interface was almost the only multi-functional interface that supported both high-speed data transmission and video/audio transmission. That is, it has both USB and DP or HDMI/DVI/VGA functions. And because its bandwidth reaches two-way 10Gbps (Thunderbolt 2 is two-way 20Gbps), it can be said to be a very advanced interface expansion technology.
