Which bwtter:Thunderbolt 4 VS USb4.0

  With the continuous advancement of technology, new interface technologies and standards are emerging one after another, the most eye-catching of which are undoubtedly Thunderbolt 4 (Thunderbolt 4) and USB4.0. They both claim to offer unprecedented data transfer speeds and video performance, so which one is better?

  First, let’s take a look at Thunderbolt 4. Thunderbolt 4 is an Intel technology that is based on the DisplayPort protocol and integrates the USB-C physical form. This means Thunderbolt 4 devices can provide extremely high bandwidth to support high-resolution displays and high-speed data transfer. According to official data, the maximum transmission speed of Thunderbolt 4 can reach 40Gbps, which is much faster than the previous generation USB 3.2 Gen 2×2 speed.

  In addition, Thunderbolt 4 also supports video output and can drive two 4K displays or one 5K display at the same time. All these features make Thunderbolt 4 an ideal choice for professional and high-performance users.

  However, to realize the functions of Thunderbolt 4, the device must have corresponding hardware and software support, which undoubtedly increases the cost. Moreover, Thunderbolt 4 is far less popular than USB, which may limit its scope of use.

  Then, we have USB4.0. USB4.0 is the latest version of the USB interface. It also supports high-speed data transmission, and the maximum transmission speed can reach 40Gbps. However, unlike Thunderbolt 4, USB 4.0 is based on the USB PD (Power Delivery) protocol, which enables it to provide higher power delivery capabilities and is more suitable for large-capacity data transmission and device charging. At the same time, the compatibility of USB4.0 devices is also very good. Almost all devices support the USB interface, which makes it very popular among ordinary users.

  However, the weakness of USB4.0 is that its performance may not be as good as Thunderbolt 4. Although the theoretical maximum transmission speed of the two is the same, in practical applications, USB4.0 may be slightly inferior.

  In summary, Thunderbolt 4 and USB4.0 each have their own advantages and disadvantages. If you need a high-performance, high-resolution interface, Thunderbolt 4 may be a better choice. However, if you need an interface with strong compatibility and fast charging speed, USB4.0 may be a better choice. Whichever one you choose, you need to decide based on your specific needs.
