As with just about any new Apple product release, iFixit has torn apart the Thunderbolt cable. Why a boring cable? iFixit has revealed that the new Thunderbolt cable actually has active chips inside, making transfers faster.
We found two Gennum GN2033 chips in the connector, one on each side. They were flanked by other, much smaller chips that surely added to the cable’s cost: two chips labeled S6A 1JG on one side, and chips labeled 1102F SS8370 and 131 3S on the other. Of course, there were tons of little resistors (providing impedance as needed) all around the larger chips.
