Introduction to the differences between Thunderbolt 4 and USB4- ChangZhou Elec IMP&EXP Co.,LTD.

Thunderbolt 4 interface

The Thunderbolt interface was developed and customized by Intel and Apple. It combines PCIExpress data transmission technology and DisplayPort display technology. It can transmit data, connect external monitors, charge external devices and other features. What are the similarities and differences between Thunderbolt4, Thunderbolt3 and USB4?

Among them, Thunderbolt 3 has an ultra-high-speed data transmission rate of up to 40Gbps; as a video output interface for an external display, it can connect two 4K/60Hz displays, one 5K/60Hz or one 4K/120Hz display, bringing a higher-definition audio-visual experience. ; The Thunderbolt 3 interface can also charge external devices such as laptops, mobile phones, and tablets, with a maximum power supply capacity of up to 100W.

Thunderbolt 4 is an iterative version of Thunderbolt 3, with some improvements based on Thunderbolt 3.

① Video. When a monitor is connected, support is available for two 4K displays or one 8K display simultaneously.

② Data. In scenarios such as connecting external graphics cards and hard drives, the minimum PCI-E transmission speed is increased from 16Gbps to 32Gbps, and when connecting to storage devices, the speed can reach 32GB/s, further narrowing the difference with direct connection to the motherboard.

③ Extension. Supports 4-port docking station and up to 2-meter data cable. One cable can be expanded to 3 Thunderbolt 4 interfaces, allowing more devices to be connected at one time.

④ Charging. Computers equipped with Thunderbolt 4 interfaces must have at least one interface for charging devices.

⑤ Wake up. With the dock connected, the computer can be woken from sleep by touching the keyboard or mouse.
