Thunderbolt 5 cable with 120 Gbps bandwidth

This Thunderbolt 5 cable delivers up to 120 Gbps bandwidth using Bandwidth Boost, tripling the throughput of Thunderbolt 4. It supports 8K resolution, 4K at 540 Hz, or triple 4K at 144 Hz displays. The 3.3 ft length connects laptops, monitors, and peripherals with a single USB-C link.

Thunderbolt 5 interface practical limits

Bandwidth Boost activates automatically when the host and device negotiate the extended 120 Gbps mode; otherwise the link runs at 80 Gbps. Display output scales to the panel's native timing up to the stated ceilings. Power Delivery negotiates up to 240 W, so actual charging speed depends on the source and sink capabilities.

Capacity and headroom for creative workloads

The 120 Gbps pipe comfortably handles multi-stream 4K editing, high-frame-rate gaming captures, and large project transfers without saturating the link. Triple 4K at 144 Hz fits within the bandwidth envelope, while an 8K panel leaves headroom for simultaneous data traffic. Charging tops out at 240 W, covering most mobile workstations but not the highest-wattage desktop replacements.

Questions about this item

Should I choose the 3.3 ft length or a longer cable?

This model is only offered in a 3.3 ft length, which keeps the signal path short for the full 120 Gbps bandwidth and 240 W power delivery.

What does the 120 Gbps figure mean when I plug the cable into my laptop?

With Bandwidth Boost the cable can reach 120 Gbps, otherwise it runs at 80 Gbps, supporting up to 8K resolution or triple 4K displays at 144 Hz.

How does the Thunderbolt interface cap the cable's performance in practice?

Thunderbolt 5 provides up to 120 Gbps with Bandwidth Boost and 240 W Power Delivery, while remaining backward compatible with Thunderbolt 4, Thunderbolt 3, USB4, USB 3.2 and USB 3.0 ports.
