The advantages of USB4 and the difference from Thunderbolt 4

The many advantages of USB4

In addition to the transmission speed of 40Gbps, USB4 has three major advantages.

USB4 supports Displayport 2.0 in alternate mode, which enables the interface of USB4 protocol to output HDR10 color 8K60Hz resolution. Although many people think that 8K is useless now, it is also backward compatible with 4K 144Hz and 4K 120Hz, which is still very practical for gamers.

Some USB4 devices can also be used with Thunderbolt 3 devices and are compatible with each other.

What is even rarer is that the products of the USB4 solution can support both USB interface and video interface transmission, which means that while outputting high-resolution video, you can also connect peripherals, and the bandwidth is absolutely sufficient.

The difference between USB4 and Thunderbolt 4

In the early days, to get devices equipped with Thunderbolt 4 ports, manufacturers had to obtain certification from Intel, which took time and money. Therefore, the Thunderbolt 4 interface will only be seen on some high-priced laptops, such as the MacBook Pro series.

But now USB4 only needs to be certified by the USB-IF organization, there are no other patent fees, and the price can be reduced a lot. For example, the price of a 0.8m Thunderbolt 4 data cable is 299 yuan, while the 0.8m USB4 data cable is only 188 yuan, and these two cables can also be used in general.
