FAQ

What is Thunderbolt™ technology?

Users have long wanted desktop-level performance from a mobile computer. Thunderbolt was developed to create new user experiences by simultaneously supporting the fastest data and most video bandwidth available on a single cable, while also supplying power.

What is Thunderbolt™ 4?

Thunderbolt 4 builds on the innovation of Thunderbolt 3 for a truly universal cable connectivity experience. Thunderbolt 4 always delivers 40 Gbps speeds and data, video and power over a single connection. It is the most comprehensive Thunderbolt specification yet with compliance across the broadest set of industry-standard specifications – including USB4, DisplayPort and PCI Express (PCIe) – and is fully compatible with prior generations of Thunderbolt and USB products.

Why is Thunderbolt™ the best USB-C for docking?

Now, one compact port provides Thunderbolt 3 data transfer, support for two 4K 60 Hz displays, and quick notebook charging up to 100W with a single cable. Also, any Thunderbolt or USB dock can connect to a Thunderbolt 3 computer making it the most advanced and versatile USB-C docking port available.

Can I connect a Thunderbolt™ device to a USB computer port?

For full compatibility a Thunderbolt™ device should be plugged into a Thunderbolt computer port. Some functionality may be available over a USB-C port depending on its implementation, but cannot be guaranteed.

Are Thunderbolt™ 4 PCs backwards compatible with Thunderbolt™, Thunderbolt™ 2, or Thunderbolt 3 based accessories?

Accessories built to Thunderbolt and Thunderbolt 2 specifications are not supported by Thunderbolt 4 PCs.
Accessories built to the Thunderbolt 3 specification are fully supported by Thunderbolt 4 PCs.

What are the video formats supported by Thunderbolt™ 3?

Thunderbolt 3 is based on the DisplayPort 1.2 specification and can support up to 2 streams (eight lanes) of DisplayPort 1.2 video bandwidth. A single cable now provides four times the data and twice the video bandwidth of any other cable, while also supplying up to 100W of power. One 4K display (4096 x 2160) 30-bit @ 120 Hz One 5K display (5120 x 2880) 30-bit @ 60 Hz Two 4K displays each (4096 x 2160) 30-bit @ 60 Hz
