The world of high-speed connectivity can be a complex and confusing place, especially when it comes to understanding the differences between various technologies. Two such technologies that often get mentioned together are USB 3.2 Gen 2 and Thunderbolt. While they may seem similar, they are not the same thing. In this article, we’ll delve into the details of each technology, exploring their history, capabilities, and applications, to help you understand the key differences between them.
A Brief History of USB and Thunderbolt
Before we dive into the specifics of USB 3.2 Gen 2 and Thunderbolt, it’s essential to understand the history behind these technologies.
USB, or Universal Serial Bus, has been around since the mid-1990s. It was designed to provide a standardized way for devices to connect to computers, replacing the multitude of connectors and interfaces that existed at the time. Over the years, USB has undergone several revisions, with each new version offering faster speeds and improved capabilities.
Thunderbolt, on the other hand, is a more recent technology, developed by Intel in collaboration with Apple. It was first introduced in 2011 as a way to provide a high-speed interface for connecting peripherals to computers. Thunderbolt was designed to be faster and more versatile than USB, with the ability to support multiple protocols and devices.
USB 3.2 Gen 2: The Fastest USB Yet
USB 3.2 Gen 2 is the latest revision of the USB standard, offering speeds of up to 20 Gbps (gigabits per second). This is a significant improvement over the previous USB 3.2 Gen 1, which topped out at 5 Gbps. USB 3.2 Gen 2 is also backward compatible with earlier USB versions, making it a versatile and widely supported technology.
One of the key features of USB 3.2 Gen 2 is its ability to support multiple lanes of data transfer. This allows for faster speeds and improved performance, especially when transferring large files or streaming high-definition video.
Key Features of USB 3.2 Gen 2
- Speeds of up to 20 Gbps
- Backward compatible with earlier USB versions

Conclusion
In conclusion, while USB 3.2 Gen 2 and Thunderbolt are both high-speed technologies, they are not the same thing. USB 3.2 Gen 2 is a fast and versatile technology that is widely supported, but it is not as fast or versatile as Thunderbolt. Thunderbolt, on the other hand, is a high-speed interface that offers speeds of up to 40 Gbps and supports multiple protocols and devices.
When choosing between USB 3.2 Gen 2 and Thunderbolt, consider your specific needs and applications. If you need a fast and reliable technology for general-purpose computing and file transfers, USB 3.2 Gen 2 may be the better choice. However, if you need a high-speed interface for demanding applications such as video editing or 3D modeling, Thunderbolt may be the better choice.
Ultimately, the choice between USB 3.2 Gen 2 and Thunderbolt will depend on your specific needs and requirements. By understanding the key differences between these technologies, you can make an informed decision and choose the best technology for your needs.
What is the main difference between USB 3.2 Gen 2 and Thunderbolt?
The main difference between USB 3.2 Gen 2 and Thunderbolt lies in their data transfer speeds and capabilities. USB 3.2 Gen 2 offers speeds of up to 20 Gbps, while Thunderbolt 3 offers speeds of up to 40 Gbps. This makes Thunderbolt 3 twice as fast as USB 3.2 Gen 2. Additionally, Thunderbolt 3 can also support multiple 4K displays and up to 100W of power delivery, making it a more versatile option.
In terms of compatibility, USB 3.2 Gen 2 is widely supported by most devices, while Thunderbolt 3 is mainly supported by high-end devices, such as Apple Macs and some Windows laptops. This limited compatibility may make Thunderbolt 3 less accessible to some users. However, for those who need high-speed data transfer and multiple display support, Thunderbolt 3 is the better option.
Is USB 3.2 Gen 2 faster than Thunderbolt 2?
Yes, USB 3.2 Gen 2 is faster than Thunderbolt 2. While Thunderbolt 2 offers speeds of up to 20 Gbps, USB 3.2 Gen 2 also offers speeds of up to 20 Gbps. However, USB 3.2 Gen 2 is a more recent technology and is widely supported by most devices, making it a more practical option for most users.
In contrast, Thunderbolt 2 is an older technology that is mainly supported by older devices. While it may still offer fast data transfer speeds, its limited compatibility and older technology make it less desirable than USB 3.2 Gen 2. Additionally, USB 3.2 Gen 2 is also more affordable than Thunderbolt 2, making it a more cost-effective option for users who need fast data transfer speeds.
Can I use a Thunderbolt 3 cable with a USB 3.2 Gen 2 device?
Yes, you can use a Thunderbolt 3 cable with a USB 3.2 Gen 2 device, but it will only work at USB 3.2 Gen 2 speeds. Thunderbolt 3 cables are designed to work with both Thunderbolt 3 and USB 3.2 Gen 2 devices, but they will only deliver the maximum speed supported by the device.
In other words, if you use a Thunderbolt 3 cable with a USB 3.2 Gen 2 device, it will only deliver speeds of up to 20 Gbps, which is the maximum speed supported by USB 3.2 Gen 2. However, if you use the same cable with a Thunderbolt 3 device, it will deliver speeds of up to 40 Gbps. This makes Thunderbolt 3 cables a versatile option for users who need to connect multiple devices with different speeds.
Is Thunderbolt 3 compatible with USB-C?
Yes, Thunderbolt 3 is compatible with USB-C. In fact, Thunderbolt 3 uses the same USB-C connector as USB 3.2 Gen 2. This means that any device with a USB-C port can potentially support Thunderbolt 3, but it’s not a guarantee.
To confirm whether a device supports Thunderbolt 3, you need to check the device’s specifications or documentation. Some devices may only support USB 3.2 Gen 2 over USB-C, while others may support both USB 3.2 Gen 2 and Thunderbolt 3. Additionally, some devices may require a separate Thunderbolt 3 controller to support Thunderbolt 3 speeds.
Can I use a USB 3.2 Gen 2 cable with a Thunderbolt 3 device?
Yes, you can use a USB 3.2 Gen 2 cable with a Thunderbolt 3 device, but it will only work at USB 3.2 Gen 2 speeds. Thunderbolt 3 devices are designed to work with both Thunderbolt 3 and USB 3.2 Gen 2 cables, but they will only deliver the maximum speed supported by the cable.
In other words, if you use a USB 3.2 Gen 2 cable with a Thunderbolt 3 device, it will only deliver speeds of up to 20 Gbps, which is the maximum speed supported by USB 3.2 Gen 2. However, if you use a Thunderbolt 3 cable with the same device, it will deliver speeds of up to 40 Gbps. This makes it important to use the correct cable to get the maximum speed supported by your device.
Is Thunderbolt 3 worth the extra cost?
Whether Thunderbolt 3 is worth the extra cost depends on your specific needs and requirements. If you need high-speed data transfer, multiple display support, and up to 100W of power delivery, then Thunderbolt 3 may be worth the extra cost.
However, if you only need fast data transfer speeds and don’t require the additional features of Thunderbolt 3, then USB 3.2 Gen 2 may be a more cost-effective option. Additionally, Thunderbolt 3 devices and cables are generally more expensive than USB 3.2 Gen 2 devices and cables, so you need to consider the overall cost of ownership when deciding which option is best for you.
Will Thunderbolt 4 replace Thunderbolt 3?
Yes, Thunderbolt 4 is the latest version of the Thunderbolt technology and is designed to replace Thunderbolt 3. Thunderbolt 4 offers the same speeds as Thunderbolt 3, but with additional features such as mandatory certification, longer cable lengths, and improved security.
Thunderbolt 4 is also designed to work with the latest USB4 technology, which offers speeds of up to 40 Gbps. This makes Thunderbolt 4 a more versatile option for users who need high-speed data transfer and multiple display support. However, it’s worth noting that Thunderbolt 3 devices will still work with Thunderbolt 4 cables and devices, but they will only deliver the maximum speed supported by the device.
