Thunderbolt 3
The most powerful and versatile port ever.
Thunderbolt 3 combines ultra-high bandwidth with the ultra‑versatility of the USB-C industry standard to create one revved‑up universal port. It integrates data transfer, charging, and video output in a single connector, delivering up to 40Gb/s of throughput for twice the bandwidth of Thunderbolt 2. Both sizes of MacBook Pro are available with up to four ports, so you can do all of that from either side. Existing devices are easily connected with a cable or adapter. And Thunderbolt 3 is reversible, so no matter how you plug in, it’s always right side up.
