Thunderbolt and Full-Featured Type C have significant differences not only in their benchmark transfer speeds but also in their data transmission modes.
Full-Featured Type C divides the 4 pairs of differential lines into 2 pairs for USB data and 2 pairs for video data. This allows for the implementation of both data and video functionalities.
On the other hand, Thunderbolt utilizes all 4 pairs of differential lines for data and video transmission, without distinguishing between PCIe and video data.
The main distinction lies in how the data is handled. At the transmitting end, PCIe data and video data are separately packaged and transmitted together in sequential order. At the receiving end, the Thunderbolt chip separates the mixed PCIe and video data back into their original forms.
This approach enables the transmission of all data using the 4 lanes available.
