Apple's US$129 Thunderbolt Pro Cable: 4 reasons why it's so expensive
1. Exceptional ingress protection
While those lucky enough to get their hands on the Thunderbolt 4 Pro Cable likely won’t be tearing it apart anytime soon, youtuber ChargerLAB thankfully conducted a thorough teardown of the 1.8-meter variant on his YouTube channel.
In the video, the content creator notes that the woven exterior of the cable is both waterproof and dustproof. Could Apple’s new cable be worthy of an IP rating?
2. Conductivity meets backward compatibility
Beneath the liquid and dust-tight seal, the content creator also uncovered a total of 19 wires, noting that five of which were high-quality tinned copper wires for driving power.
The majority of the wires in the Thunderbolt 4 Pro Cable are plated with pure copper and silver, while two plastic-clad wires enable USB 2.0 transmission for backward compatibility with standard USB and Thunderbolt 3.
3. Robustly reinforced
The inside of the connector on the Thunderbolt 4 Pro Cable additionally features 24 gold-plated pins that are shielded by a brass sleeve and strong black plastic.
These protections enhance the long-term durability of the connector by reducing the risk of damage or interference, especially when connected to compatible portables like the latest-gen MacBook Pro.
4. Intel (still) inside
While the Cupertino giant is still in the midst of transitioning its Mac lineup to Apple silicon, Intel chips remain a key part of Thunderbolt workflows for the time being and the Thunderbolt 4 Pro Cable is no exception.
The Intel chip inside the cable directs the Thunderbolt connection while serving to reduce jitter by acting as a signal reconstructor while feeding data to monitors such as Apple's new Studio Display.
