Apple Thunderbolt 4 Pro cable CT scan by Lumafield
Lumafield used a powerful X-ray CT scanner to determine why Apple’s Thunderbolt 4 Pro cable is $129 compared to Amazon’s cheaper USB-C offerings.
It has 12 pins instead of 24, with eight of them jumped across for cost-cutting. This is a lower-spec cable, so the cheaper construction and engineering are warranted, but it helps show exactly why Apple’s design costs more than ten times as much.
