Thunderbolt, the ultra-fast Intel-developed interface, will soon double in speed. Intel demoed the Falcon Ridge Thunderbolt controller Monday at NAB, the annual National Association of Broadcasters’ trade show in Las Vegas. The new design, named Thunderbolt 2, promises to double Thunderbolt’s current speeds from 10 Gbps to 20 Gbps, which equals a theoretical maximum transfer rate of 2,560 megabytes per second. The jump in performance is necessary to accommodate the video production industry, which is quickly moving to 4K resolutions
