Apple's new Thunderbolt 4 USB-C cable costs a staggering $130, more than ten times the price of a generic USB-C cable. But what's the difference between Thunderbolt and USB-C? Adam is joined by electrical engineer Zach Radding to examine Lumafield's CT scans of Apple's cable as well as three non-Thunderbolt USB-C cables to understand the engineering and components that make up these cables. This video is part of a sponsored series with Lumafield.
