The maximum transfer rate of USB4.0 is 40Gbp, and the theoretical speed is 5000MB per second. The biggest highlight of USB4.0 is that it supports Intel Thunderbolt protocol and is backward compatible with USB3.0 and 2.0 protocols.

What is the transfer speed of USB 4.0?

The maximum transfer rate of USB4.0 is 40Gbps, the theoretical speed is 5000MB per second, and the speed is 8 times that of USB 3.0. USB 4.0 will redefine the multi-terminal device sharing and single-channel high-speed link connection scheme, and has the ability to automatically expand data distribution, so it does not affect each other during multiple data transmissions. The biggest highlight of USB4.0 is that it supports Intel Thunderbolt protocol and is backward compatible with USB3.0 and 2.0 protocols.

The new USB 4.0 still uses the USB-C interface, and the power supply will reach 100W. The USB4 interface can also support PCIE devices, such as external graphics cards and external monitors.
