Why two identical USB-C cables can have vastly different speeds
In short: A physical connector does not guarantee a specific performance level. This video explains why the same plug can support everything from basic charging to ultra-fast data transfer, and what internal factors actually dictate your cable's speed.
While USB-C is the universal physical standard for connectors, it does not define the internal capabilities of the cable. A single port can be used by cables supporting various USB generations, each with distinct data rates and electrical requirements.
The video explores why some cables are capped at 480Mbps while others reach speeds like 10Gbps, 20Gbps, 40Gbps, or even 80Gbps. It highlights that speed is determined by the cable's specific signal pathways and hardware specifications rather than just the shape of the plug.
