What protocols does USB4 support?
USB4 is the latest version of USB connector technology, which provides faster data transfer and excellent connectivity. USB4 not only provides better port utilization, but also thanks to its USB-C connector, it also provides data transfer speeds of up to 40 Gbps and 100 watts of power. This means you can transfer the largest files in seconds and charge your devices at lightning speed.

USB4 supports multiple protocols, which make USB4 powerful in data transfer, video transmission, and power transmission. Specifically, the protocols supported by USB4 mainly include the following aspects:
USB protocol: USB4 is backward compatible with older versions of USB protocols such as USB 3.2, USB 3.1, USB 3.0, and USB 2.0. This means that the USB4 interface can connect and recognize these older versions of USB devices, ensuring a wide range of device compatibility.
Thunderbolt protocol: The basic protocol of USB4 adopts the Thunderbolt 3 protocol specification that Intel has thoroughly disclosed. This has greatly improved the performance of USB4, especially in terms of data transfer speed and bandwidth. USB4 achieves a transmission speed of up to 40Gbps (or even higher, such as 80Gbps or 120Gbps, depending on the version and standard) by integrating the Thunderbolt protocol, providing strong support for high-speed data transmission.
DisplayPort protocol: USB4 supports the DisplayPort video transmission protocol, which means that the USB4 interface can directly connect and drive high-resolution displays. Through the DisplayPort tunneling protocol, USB4 can transmit data and video signals simultaneously on a single interface, greatly simplifying the complexity of device connection.
PCI Express (PCIe) protocol: USB4 also supports the PCI Express protocol, which allows the USB4 interface to connect high-speed PCIe devices such as external GPUs, high-speed storage devices, etc. The high-speed transmission capability of the PCIe protocol further enhances the overall performance of USB4, providing users with richer connection options and higher data transmission speeds.
USB Power Delivery (USB PD) protocol: USB4 also supports the USB PD protocol, which is the power transmission protocol. This allows the USB4 interface to not only transmit data and video signals, but also provide power support for connected devices. The USB PD protocol supports high-power power transmission, which can meet the charging and power supply needs of more and more devices.
USB4 integrates multiple functions such as high-speed data transmission, video transmission, and power transmission by supporting multiple protocols, providing users with a more convenient and efficient connection experience. The support of these protocols also makes USB4 have broad application prospects in many fields, such as games, video editing, professional workstations, and other scenarios that require high-speed data transmission and multiple device connections.
