The cost of Thunderbolt 5 cables can be several times higher than standard USB-C cables due to their advanced technology. The latest Thunderbolt standard allows for impressive data transfer rates, supporting up to 80 Gbps bidirectionally and up to 120 Gbps in boost mode, enabling the transfer of 1TB of data in minutes. In comparison, typical USB 2.0 connections would require several hours for the same task.
Thunderbolt 4 cables offer a maximum of 40 Gbps, while certified Thunderbolt 5 cables can handle charging up to 240W via USB Power Delivery, compared to the 100W maximum of Thunderbolt 4. The engineering behind these cables is crucial, as they include integrated circuits to ensure signal integrity over longer distances, often requiring "active" designs to maintain performance.
While many existing USB-C cables only support basic data transfer speeds, Thunderbolt cables excel in facilitating high-speed connections to multiple 8K displays and external GPUs, making them suitable for demanding tasks and high-performance devices. The investment in Thunderbolt technology reflects its superior capabilities in data handling and power delivery.
