What is a Thunderbolt 4 Pro cable?
According to Lumafield, the cable is a versatile connector that meets a wide spectrum of data transfer and charging requirements. It supports Thunderbolt 3, Thunderbolt 4, and USB 4 data transfers with speeds of up to 40 GB/s. “It also features DisplayPort video output (HBR3) and can charge devices at up to 100W, exceeding most data and power requirements,” Lumafield said in a blog post.
What makes cable more expensive?
According to Lumafield, the connector has a hard plastic casing; Beneath this is a metal shield that is completely bonded to the connector shell – all made of stainless steel. “Where the cord leaves the connector, we get a single-piece strain relief from eight different directions that shields the entire bottom of the assembly,” Lumafield said. Additionally, the Thunderbolt connector is maxed out at almost every point; It has 24 pins, all mounted independently on a 10-layer PCBA.
In comparison, the really basic – and much cheaper – Amazon Basics cable has 12 pins and four pairs of them connected to each other rather than individually to the PCBA. This means that it ensures that Apple’s cable offers faster data speeds than others.
Lumafield calls the Thunderbolt cable “a stunning piece of precision engineering.” So, there you have it: the precision engineering is what makes this Apple cable more expensive than others.
