USB is the most popular electronic device interface on the earth, but after entering the USB 3.x era, due to various reasons, the popularity of new standards has slowed down significantly, especially the latest USB4, which has been released for two and a half years, and is still not commercial.
USB4 is actually based on Intel's contribution of Raiden 3, the bandwidth doubled to 40Gbps, the interface form is only Type-C, maintaining backward compatibility.
Intel has little interest in this kind of USB4 that does not change the soup, and has been focusing on promoting its own Thunderbolt 4, including the latest 12th-generation Core platform.
AMD's Ryzen™ 6000H/U series mobile platform will first support USB4, and new notebooks will appear in the near future.
However, AMD also focuses on USB4 support, currently mainly focused on Linux systems, update iteration speed is very fast, the latest addition is USB4 DisplayPort Tunneling, and more USB4/Raiden support.
AMD is rebuilding the support for the Linux kernel, especially the "is_thunderbolt" assignment in the driver, which was originally defined by Intel, which was previously connected to the PCIe bus, and will be connected to the Thunderbolt interface in the future.
The benefit of this is that USB4-connected devices are hot-swappable and support more and flexible external device connections.
The USB4 DisplayPort Tunneling tunneling mechanism enables the same signal to be transmitted by the USB Type-C data cable, reducing the number of hardware devices and transmitting more signals in a single independent data cable.
In addition, AMD recently submitted 12 patches to the Linux kernel, simplifying and enhancing support for external graphics cards.
As for the support under Windows, AMD has no public action, but since the device is about to appear, I believe it is also ready.
