The Thunderbolt 4 interface is a high-speed data transmission interface that was first released in 2019 and is used to connect high-performance devices. The Thunderbolt 4 interface has been improved and upgraded on the basis of the previous generation Thunderbolt 3 (Thunderbolt 3), and has the following features:
1. Higher bandwidth: Thunderbolt 4 provides a higher data transmission rate, supporting up to 40 Gbps data transmission, which is twice that of Thunderbolt 3.
2. More connections: Thunderbolt 4 supports up to 4 external displays, two of which support displays up to 8K resolution, and the other two support displays up to 4K resolution.
3. Greater compatibility: Thunderbolt 4 is compatible with other USB 4 and DisplayPort standards, making it easier to work with other devices in the future.
4. Higher power transmission capability: Thunderbolt 4 can provide up to 100 W of charging power for devices, which makes it possible to power high-performance devices such as laptops through the Thunderbolt interface.
5. Better security: Thunderbolt 4 provides stronger data protection and security features, such as PCIe data protection and authentication mechanisms, to ensure the security and integrity of data transmission.
6. Lower latency: Thunderbolt 4 introduces a new data buffer, which reduces the delay in data transmission and improves the efficiency of data transmission.
7. Compatible with Intel Arc GPU: Thunderbolt 4 supports connecting to Intel Arc GPU, providing users with more powerful graphics performance and a wider range of connection options.
The Thunderbolt 4 interface has been significantly improved in terms of speed, compatibility, security and functionality, providing users with a better user experience.
