Mini DisplayPort and Thunderbolt use the same connector interface but are actually different cables. Thunderbolt cables have a chip built into the connector and run two independent channels at a data-transfer speed of 10Gbps per channel (totaling 20Gbps). Mini DisplayPort is a passive cable which uses 4 channels and runs at a speed of 5.4Gbps per channel (totaling 21.6Gbps).
Our mini DisplayPort cables can be used in the following applications:
Mini DisplayPort cables cannot be used in the following applications:
A mini DisplayPort source is not compatible with a Thunderbolt monitor regardless of the cable being used.
