What is the difference between Thunderbolt 3 and USB Type-C
There are many differences between Thunderbolt 3 and USB Type-C. Here is a detailed comparison of the two:
1. Interface specifications and standards
Thunderbolt 3:
It is a hardware interface standard that combines data, video, audio, and power into a single connection.
Based on the USB-C physical interface, but provides higher performance and more features.
USB Type-C:
It is a new USB interface specification designed to provide higher data transfer speeds and stronger power transmission capabilities.
Its interface is slim in design, supports both sides of the plug, and can withstand repeated plugging and unplugging.

2. Data transfer speed
Thunderbolt 3:
The maximum data transfer speed can reach 40 Gbps, far exceeding the normal speed of USB Type-C.
Supports high-speed protocols such as PCI Express and DisplayPort, which can achieve high-speed data transfer and video output.
USB Type-C:
When based on the USB 3.1 specification, the maximum data transfer speed is 10 Gbps (USB 3.1 Gen 2).
It also supports lower versions of protocols such as USB 2.0 and USB 3.0, but the speed is correspondingly slower.
3. Power transmission capability
Thunderbolt 3:
Provides up to 100W of power transmission capability, which can power and charge devices through a single cable.
USB Type-C:
Standard cables support 3A current, and the interface supports 5A current, which can provide a certain power transmission capability.
Support USB Power Delivery specification for more efficient charging and power management.

4. Compatibility and application scenarios
Thunderbolt 3:
Mainly used in high-end devices that require high-speed data transmission and large power supply, such as professional laptops, external graphics card boxes, high-speed storage devices, etc.
Due to its high performance and compatibility, Thunderbolt 3 devices are usually more expensive.
USB Type-C:
Widely used in various consumer electronic devices, such as smartphones, tablets, laptops, etc.
Due to its slim interface design and reversible pluggable features, USB Type-C has become a standard interface for many devices.
Conclusion
Thunderbolt 3 and USB Type-C have significant differences in interface specifications, data transmission speed, power transmission capacity, compatibility, and application scenarios. Thunderbolt 3 is known for its higher performance and more functions, and is suitable for high-end devices that require high-speed data transmission and large power supply; while USB Type-C is popular for its wide compatibility and convenience, and has become a standard interface for many consumer electronic devices. When choosing which interface to use, you should weigh it according to the specific application scenarios and needs.
