Engadget reports that Intel has announced the next generation of Thunderbolt, promising throughput of 20 Gbps in each direction -- twice as fast as the current protocol, allowing simultaneous 4K video file transfer and display
The new generation of Thunderbolt, code-named 'Falcon Ridge', will be backwards compatible with current-generation cables and connectors. Intel expects production to ramp up in 2014.
An on-stage demo with fresh-off-the-press silicon showed the new Thunderbolt running 1,200 [MB/sec], which is certainly a step up from what's currently on the market.
