Thunderbolt 3 offers a connection with state-of-the-art speed and versatility. Delivering twice the bandwidth of Thunderbolt 2, it consolidates data transfer, video output, and charging into a single compact connector. And with the integration of USB-C, convenience is added to the speed of Thunderbolt to create a truly universal port.

1. Type: PCI Express to Thunderbolt; External Ports: 2 x Thunderbolt 3 port (type C). A prime example is the latest MacBook Pro, which, while offering great performance, lacks the PCIe expansion slots necessary to support specialty cards that connect pro video and audio inputs, transcode data, and connect to high-speed storage and networks.
2. Use PCIe Expansion Cards with any Thunderbolt Equipped Mac or Windows Mercury Helios is the ideal way to access your PCIe cards and is perfect for video capture and editing, media transcoding, audio workflows, ultra-fast networking, data storage, and more via its Thunderbolt 2 interface.
3. Desktop and rackmount systems and compact portable boxes to connect PCIe cards to Mac and Windows computers with Thunderbolt 2 ports. Rackmount server enclosure for Mac Pro and Mac mini (with Thunderbolt 2 ports).

Transferring data at speeds of up to 40Gb/s, which is two times faster than Thunderbolt 2 and eight times faster than USB 3, Thunderbolt 3 delivers the fastest connection to any dock, display, or device. You can also daisy-chain up to six Thunderbolt devices through a single port without needing a hub or a switch. So connecting a storage device to your computer, and then a display to your storage device, works as it’s meant to — with powerful throughput.⁸

Less than one minute to copy 25,000 photos

6K resolution. 20.4 million pixels.
One remarkable cable.

Thunderbolt 3 provides twice the display bandwidth of Thunderbolt 2, enabling your Mac to support up to four 4K displays or up to two 6K displays.¹ Which means that with two Thunderbolt controllers in the 16-inch MacBook Pro, you can send graphics to dual 6K displays for the perfect high-resolution photo and video editing setup. Thunderbolt 3 connects to DisplayPort displays and monitors with a cable, while supporting HDMI and VGA displays with the use of an adapter.

With Thunderbolt 3, a single USB-C port can deliver power in both directions. So a port can charge a device or, alternatively, be charged by one. And it’s capable of delivering up to 100 watts of power, so a single cable can be used to connect to a dock or display and charge your MacBook Pro or MacBook Air simultaneously.
