What’s the fastest way to get 4K video in and out of a PC for editing? With Thunderbolt 2.
The new interface standard is backward-compatible with the original Thunderbolt, but the controller combines two bidirectional channels to achieve throughput of a staggering 20Gb/s (USB 3.0, in comparison, offers throughput of 5Gb/s).
And since Thunderbolt 2 incorporates the DisplayPort 1.2 specification, PCs equipped with the port will be able to transfer 4K video (resolutions up to 3840 by 2160 pixels) to and from an attached Thunderbolt 2 peripheral and output that video to a single 4K display at the same time. (Thunderbolt and DisplayPort 1.2 can daisy-chain as many as three lower-resolution—up to 1920 by 1200-pixel—displays).
