The world of computer connectivity has witnessed a significant transformation in recent years, with the introduction of new standards that promise faster speeds, higher bandwidth, and greater versatility. Two of the most talked-about technologies in this space are USB4 and Thunderbolt. While they share some similarities, they are not identical, and understanding their differences is crucial for making informed decisions when it comes to choosing the right connectivity solution for your needs.
What is USB4?
USB4 is the latest generation of the Universal Serial Bus (USB) standard, which was introduced in 2020. It is designed to provide faster speeds, higher bandwidth, and greater versatility than its predecessors, USB 3.2 and USB 3.0. USB4 is based on the Thunderbolt 3 protocol and offers speeds of up to 40 Gbps, which is twice as fast as USB 3.2. It also supports multiple data and display protocols, including USB, DisplayPort, and PCIe.
One of the key features of USB4 is its ability to support multiple displays and data devices simultaneously. This makes it an ideal solution for applications that require high-speed data transfer and multiple display outputs, such as video editing, 3D modeling, and gaming.
Key Features of USB4
- Speeds of up to 40 Gbps
- Supports multiple data and display protocols, including USB, DisplayPort, and PCIe
- Can support multiple displays and data devices simultaneously
- Backward compatible with USB 3.2 and USB 3.0 devices
- Requires a USB4-certified cable to function at full speed
What is Thunderbolt?
Thunderbolt is a high-speed connectivity standard developed by Intel in collaboration with Apple. It was first introduced in 2011 and has since become a popular choice for applications that require high-speed data transfer and multiple display outputs. Thunderbolt is based on the PCI Express (PCIe) protocol and offers speeds of up to 40 Gbps, which is similar to USB4.
Thunderbolt is known for its ability to support multiple displays and data devices simultaneously, making it an ideal solution for applications such as video editing, 3D modeling, and gaming. It also supports power delivery, which means that it can be used to charge devices such as laptops and tablets.
Key Features of Thunderbolt
- Speeds of up to 40 Gbps
- Supports multiple data and display protocols, including PCIe, DisplayPort, and USB
- Can support multiple displays and data devices simultaneously
- Supports power delivery, which means that it can be used to charge devices
- Requires a Thunderbolt-certified cable to function at full speed
USB4 vs Thunderbolt: What’s the Difference?
While USB4 and Thunderbolt share some similarities, they are not identical. Here are some key differences between the two standards:
- Speed: Both USB4 and Thunderbolt offer speeds of up to 40 Gbps, but Thunderbolt has a slight edge when it comes to real-world performance. This is because Thunderbolt is based on the PCIe protocol, which is optimized for high-speed data transfer.
- Compatibility: USB4 is backward compatible with USB 3.2 and USB 3.0 devices, while Thunderbolt is not. This means that USB4 devices can be used with older USB ports, while Thunderbolt devices require a Thunderbolt port to function.
- Power Delivery: Thunderbolt supports power delivery, which means that it can be used to charge devices such as laptops and tablets. USB4 does not support power delivery, which means that it cannot be used to charge devices.
- Certification: Both USB4 and Thunderbolt require certification to ensure that devices meet the required standards. However, Thunderbolt certification is more rigorous, which means that Thunderbolt devices are more likely to meet the required standards.
When to Choose USB4
USB4 is a good choice for applications that require high-speed data transfer and multiple display outputs, but do not require power delivery. It is also a good choice for devices that need to be backward compatible with older USB ports. Some examples of applications that may benefit from USB4 include:
- Video editing and 3D modeling
- Gaming
- Data transfer and storage
When to Choose Thunderbolt
Thunderbolt is a good choice for applications that require high-speed data transfer, multiple display outputs, and power delivery. It is also a good choice for devices that require a high level of certification and reliability. Some examples of applications that may benefit from Thunderbolt include:

What is USB4 and how does it differ from previous USB versions?
USB4 is the latest generation of the Universal Serial Bus (USB) standard, offering faster speeds and improved performance compared to its predecessors. It is based on the Thunderbolt 3 protocol and offers speeds of up to 40 Gbps, making it twice as fast as USB 3.2 Gen 2. This increased speed enables faster data transfer, making it ideal for applications that require high-bandwidth data transfer, such as video editing and 3D modeling.
One of the key differences between USB4 and previous USB versions is its ability to support multiple data and display protocols simultaneously. This means that a single USB4 port can be used to connect multiple devices, such as a monitor, keyboard, and mouse, while also transferring data at high speeds. Additionally, USB4 is backward compatible with previous USB versions, making it easy to use older devices with the new standard.
What is Thunderbolt and how does it compare to USB4?
Thunderbolt is a high-speed interface developed by Intel that offers speeds of up to 40 Gbps, similar to USB4. It is designed to provide a fast and reliable connection for devices such as external hard drives, monitors, and docking stations. Thunderbolt is known for its high-bandwidth data transfer capabilities, making it ideal for applications that require fast data transfer, such as video editing and 3D modeling.
The main difference between Thunderbolt and USB4 is that Thunderbolt is a proprietary technology developed by Intel, while USB4 is an open standard developed by the USB Implementers Forum (USB-IF). This means that Thunderbolt devices are typically more expensive than USB4 devices, and may require specific hardware and software to function. However, Thunderbolt is generally considered to be more reliable and faster than USB4, making it a popular choice among professionals who require high-speed data transfer.
