That raises question on the future of the fast, but hardly used Thunderbolt standard.
It will also have the ability of much higher throughput (40Gbps) inThunderbolt mode.
The only difference that would separate the two would be the small lightning logo on the connector itself.
The need for distinguishing mark is important as Thunderbolt works by combining electronics directly into the cable itself.
The regularUSB-C cablesclearly would not be able to carry out transfers at Thunderbolt 3 speeds.
