Start with what is physically represented
Exact manufacturer cable; host/device roles depend on setup.
Beyond the connector shape
Four evidence boundaries
Exact manufacturer example; match the named product and length.
- Electronic marker not established
- Not established
Passive construction is documented; the exact electronic marker is not separately identified in the inspected source.
- Fallback / protocol scope source conflict
- Unresolved source wording
USB3 up to 10 Gb/s is explicit, but the overview groups older Thunderbolt protocols with USB4 under 80 Gb/s. Do not distribute that number to each older protocol.

- Whole-cable certification check not established
- Not established
No exact whole-cable certification registry match or authentic-sample inspection was performed.
- Bandwidth and task scope documented
- 80/80 or display-driven 120/40 Gbit/s
Intel describes these link modes. Neither means symmetric 120 Gbit/s or measured file-copy speed on this cable.

Apple documents its 1 m Thunderbolt 5 Pro Cable as a passive USB-C-ended Thunderbolt cable supporting represented Thunderbolt/USB/display modes and charging; those capabilities belong to this exact product, not to USB-C shape generally.

Apple labels its Thunderbolt 5 Pro Cable 1 m passive and lists up to 240W charging, USB4 up to 80 Gb/s in the highlights, USB3 up to 10 Gb/s in the overview, and DisplayPort 2.1 UHBR20.

Apple’s Thunderbolt 5 cable overview groups Thunderbolt 3, Thunderbolt 4 and USB4 under an up-to-80-Gb/s phrase, while Intel’s comparison gives Thunderbolt 4 a 40-Gbit/s link. This grouped wording is not evidence that an older Thunderbolt host gains an 80-Gbit/s mode.
Scope: Unresolved scope of grouped manufacturer wording; do not distribute the largest number across every listed protocol or infer an undocumented revision explanation. · review due 2027-01-06

Apple advertises up to 120 Gb/s for its Thunderbolt 5 cable. Intel explains the technology’s high-display-bandwidth mode as 120 Gbit/s in one direction with 40 Gbit/s in the other, rather than a symmetric or measured storage-transfer rate.
Scope: Manufacturer cable advertisement interpreted with the technology brief; no actual negotiated link or workload was measured. · review due 2027-01-06
