  • Reach up to 120Gbps display bandwidth using Bandwidth Boost for smoother visuals

What the cable does and who needs it

This 1.6ft USB-C cable delivers up to 80Gbps bandwidth and 240W charging using the Thunderbolt 5 standard. It suits creators and professionals who connect dual 8K displays, high-speed storage or eGPU enclosures to a compatible host. Buyers who only need basic charging or 4K video at 60Hz will not use the extra capability.

Practical limits of the Thunderbolt 5 interface

The cable reaches 80Gbps only when both host and device support the Gen4 signalling rate; Gen3 ports top out at 40Gbps and Gen2 at 20Gbps. Video bandwidth can hit 120Gbps with Bandwidth Boost for dual 8K at 60Hz or triple 4K at 144Hz, but the connected displays and GPU must also support those modes. Backward compatibility covers USB 2.0, 3.0, 3.2 Gen1, Gen2, Gen2x2 and Thunderbolt 3, each at its native speed ceiling.

What to verify on your current setup

Confirm that your laptop, dock or desktop port is labelled Thunderbolt 5 or USB4 Version 2.0 to unlock the full 80Gbps data and 240W power ratings. Check that any monitor or eGPU enclosure accepts the target resolution and refresh rate such as 8K at 60Hz or 4K at 540Hz. Ensure the power source can supply up to 48V at 5A if you intend to charge at the maximum 240W level.
