How to Choose a Thunderbolt 4 Docking Station?
As we all know, buying a Thunderbolt 4 dock is a significant investment, and it usually costs hundreds of dollars.Therefore, it is crucial to be informed in order to make the wisest choice. After all, a Thunderbolt docking station is an upgrade for computer accessories, and no one wants an unsatisfactory upgrade. We hope this blog can provide some assistance as you go through the process of selecting a Thunderbolt docking station.
What is a Thunderbolt 4 Dock?
A docking station (or dock station) is a device designed to solve the issue of limited docking ports on laptops by expanding the available interfaces. Through a single data cable, a docking station can extend a computer's interfaces, allowing various peripheral devices such as displays, hard drives, network cards, and USB devices to be connected to the computer, thereby enhancing its expandability and usability. A Thunderbolt 4 docking station builds upon the foundation of a USB C docking station by incorporating Intel's Thunderbolt 4 technology—the integration of PCI Express data transfer technology and DisplayPort display technology, which can not only transmit data but also transmit video and audio signals and provide power supply.
USB-C Docking Station vs Thunderbolt 4 Dock
Performance
The Thunderbolt 3/4 interface can achieve a maximum transfer speed of up to 40Gbps, while the USB 3.2 Gen 2x2 transfer speed is only 20Gbps. Compared to the USB 3.2 interface (with a maximum transfer speed of 20Gbps), the Thunderbolt interface supports higher resolution and faster video output transfer speeds. It's worth noting that USB 4 docking stations are already available on the market, which, like the Thunderbolt 3/4 interface, also support transfer speeds of up to 40Gbps.
Compatibility
Thunderbolt is backward compatible with USB-C (including USB4). However, when connecting different cables/interfaces, only the lowest common data rate is supported. For example, if you connect a device that supports up to USB 3.2 to a Thunderbolt 4 port replicator, that port replicator will process and transfer data, power, and video according to the USB 3.2 standard. Additionally, because the USB-C port has multiple protocols, not all USB-C docking ports have full functionality. Some USB-C docking ports only support charging and data transfer but do not support video signal transmission.
Price
Users often ask: why are thunderbolt 4 dock so expensive? Due to the significantly higher patent fees for Thunderbolt technology compared to USB-C, such as the use of Thunderbolt chips and conducting Thunderbolt certification will require higher costs. Therefore, Thunderbolt docking stations are generally more expensive than USB-C docking stations. For example, currently, the prices of Thunderbolt 4 dock stations are much higher than those of USB 4 dock stations.
Overall, if you only need to simply expand your computer's interfaces for daily office work and multimedia entertainment, a USB-C docking station is an extremely cost-effective choice. However, for professional users, Thunderbolt 3/4 docks can provide a better performance experience.
