Engadget is reporting that Intel has introduced the next generation of the Thunderbolt interface at the NAB conference. The update promises data transfer rates of 20 Gbps in each direction on Thunderbolt's two channels, twice the speed of the current generation rated at 10 Gbps. The demonstration Engadget witnessed showed the new Thunderbolt running at 1,200 Mbps, which is simply remarkable. Intel says the new Thunderbolt is also capable of simultaneous 4k video file transfer and display.
In addition to the improved speed, the company will be introducing thinner cables for devices in the next year. Current users shouldn't worry too much about obsolete accessories; the new Thunderbolt is backwards-compatible with previous connectors and cables.
Look for the new Thunderbolt sometime in 2014.
