GoKawiilThunderbolt 5 doubles data speeds and boosts power delivery over Thunderbolt 4
Thunderbolt 5 upgrades on Thunderbolt 4 by offering up to 120Gbps in one direction and 40Gbps in the other, compared to Thunderbolt 4's symmetric bandwidth, while also supporting 240 watts of power delivery. Both standards share USB-C connectors and support data, video and power over the same cables, and Thunderbolt 5 remains backwards compatible with Thunderbolt 4, 3 and USB4 devices.
