Thunderbolt 4 and Thunderbolt 3 cables both support data transfer speeds of up to 40 Gbps, but Thunderbolt 4 offers additional features and stricter requirements. Thunderbolt 4 guarantees support for dual 4K displays or a single 8K display, and provides improved power delivery, security, and compatibility. Additionally, Thunderbolt 4 cables are required to be at least 2 meters in length while maintaining full performance.
