The ambiguous relationship between USB4 and Intel Thunderbolt interfaces has left the AMD platform in no way to suffer, but the situation may have to change.

It has been found that a new AMD GPU driver has appeared in the Linux kernel library, which adds support for USB4 transmission of DP 1.4 signals.

In terms of the general rhythm of Linux patches, Linux 5.16 is expected to add official support for USB4 DP transmission by the AMD platform. This also means thatStarting as soon as next year, the AMD platform will also have a full-featured USB4 interface.


With up to 40Gbps bandwidth, USB4 is down-compatible with the Thunderbolt 3 protocol, transmits video signals, and supports power supply up to 100W.

Previously, it was said that the Ryzen V3000 embedded processor and the Ryzen 6000H notebook processor would add support for USB 4 for the first time.
