Thunderbolt technology is an Intel-developed connectivity standard that delivers power, data, and video signals over a single connection. Thunderbolt certification establishes mandatory minimum requirements for cables, PCs, and accessories to help ensure greater reliability and interoperability across devices and vendors. For end users, Thunderbolt based products provide a great experience when connecting accessories.
In shape, Thunderbolt 4 is no different from USB type C. Both are easily recognized by the placement of the lightning bolt on the Thunderbolt, while on USB type-c there is no lightning logo.
To differentiate between USB C and Thunderbolt ports, you can see the logo printed above the connector hole. USB C usually lists the type used while Thunderbolt usually uses a lightning bolt icon.
