First, the structure of the USB cable is different between the models:
1. The USB2.0 cable is a four-pin interface (only one row of 4pin interfaces).
2.USB3.0 and USB3.1 cables are 9-pin interfaces, compared with USB2.0 cables, there are two rows of interfaces, the front 4pin interface and the back 5pin interface.
Second, the transmission rate between USB cable models is different:
1. The transmission rate of USB2.0 cable is 480Mbps (60MB/s).
2. The transmission rate of the USB3.0 cable is 5Gbps (625MB/s).
3. The transmission rate of USB3.1 cable is 10Gbps (some bandwidth supports other parts, the actual bandwidth is 7.2Gbps).
Thirdly, the supply of power between USB cable models is different:
1. The power supply of USB 2.0 cable needs 5V/0.5A.
2. USB 3.0 cable power supply needs 5V/0.9A.
3. USB 3.1 cable will increase the maximum allowable standard of power supply to 20V/5A, power supply 100W.
