Here's why cables for Thunderbolt 4 and 5 ports cost so much
Engadget · 3 min read · tech
Thunderbolt 5 cables cost more than USB-C because they include advanced signal-integrity chips and support up to 80 Gbps bidirectional data transfer (120 Gbps in boost mode), 240W charging, and can drive 8K displays or 540Hz gaming monitors. The cables use retimer chips to maintain signal quality over distance.
