Thunderbolt 4 Pro Cable

The Thunderbolt 4 Pro Cable is a heavy-duty cable produced by Apple to allow the high-speed transfer of data with supported Thunderbolt 3 and 4 devices, the display of video on Thunderbolt displays, or to be charged from a USB-C Power Adapter, sold separately.

Description
The Thunderbolt 4 Pro Cables were first announced on March 8, 2022 to support the Mac Studio. The "Pro" cables are functionally similar to the Thunderbolt 3 (USB-C) Cable, but are available in longer lengths and are encased in black braiding. Both support fast charging with up to 100 s of power. A 1.0-meter version was included with the 27-inch Studio Display. The 1.8-meter version was sold separately and began shipping at the same time as the Mac Studio. A longer 3-meter version became available for preorder on May 4, 2022 and is scheduled to be in stores on May 20.

Differences with USB-C cables
Apple's own USB-C Charge Cable looks externally similar to, and is cheaper than, the Thunderbolt 3 cables. It can also be plugged into Thunderbolt 3 and 4 ports (denoted by a Thunderbolt symbol), but its data transfer speed would be limited to that of USB 2.0 (480 Mbps). The USB-C cable also does not support carrying video signals. To achieve maximum bandwidth of up to 40 Gbps (an 80-fold improvement), a genuine Thunderbolt 3 or 4 cable would be required.

Reception
Apple was criticized for the high prices of the Thunderbolt 4 Pro Cables, but reviewers found them to be of reasonable value after assessing their durable construction for use in professional environments.
