USB4 vs. Thunderbolt 4: Do You Actually Need an Expensive Dock?
As we move deeper into the 2020s, the USB landscape is changing faster than ever. If you've been looking for a high-performance hub or docking station lately, you've likely seen labels like USB4 and Thunderbolt 4. They both look similar, use the same Type-C connector, and promise blistering speeds—but are they the same thing?
In this guide, we’ll strip away the technical jargon and help you decide which standard fits your needs and your budget.
What is USB4?
USB4 is the latest official standard from the USB Implementers Forum (USB-IF). It’s based on the Thunderbolt 3 protocol, which is a big deal because it brings high-speed data transfer (up to 40Gbps) and better resource management to the masses.
The catch? USB4 is a "modular" standard. This means a manufacturer can call a device "USB4" even if it only supports 20Gbps instead of the full 40Gbps.
What is Thunderbolt 4?
Thunderbolt 4 is Intel’s premium version of USB4. While it uses the same underlying technology, it has much stricter requirements. To get a Thunderbolt 4 certification, a device must support 40Gbps, dual 4K monitors, and wake-from-sleep functionality.
The Real-World Comparison
| Feature | USB4 | Thunderbolt 4 |
|---|---|---|
| Max Speed | Up to 40Gbps (often 20Gbps) | Guaranteed 40Gbps |
| External Displays | Supports at least one | Supports two 4K or one 8K |
| Power Delivery | Mandatory | Mandatory |
| Compatibility | Backwards compatible with USB versions | Compatible with USB4, TB3, and USB |
Do You Need an Expensive Dock?
For many users, a high-quality USB4 hub offers the best balance of performance and price. Unless you are a video editor pushing dual 6K displays or using high-end external GPUs, a well-engineered USB4 device like the BizHUB will likely handle everything you throw at it.
