Improved Thunderbolt tech jumps to 20 Gbps, supports 4K video
Intel has introduced an improved version of its <A href="">Thunderbolt</a> interface, doubling the transfer speeds to 20 Gbps upstream and downstream. With a booth at the National Association of Broadcasters expo this week, Intel notes that its next-generation Thunderbolt controller, codenamed Falcon Ridge, has the bandwidth to support 4K video file transfers while simultaneously driving a 4K display.<br />
<br />
The current Thunderbolt hardware supports 10 Gbps transfer rates in both directions, however some uncompressed 4K formats would not leave enough room to handle the display signal. <br />
<br />
The company also introduced Redwood Ridge Thunderbolt controllers for its fourth-generation Core-series processors, adding DisplayPort 1.2 capabilities, improved power management, smaller component size and reduced costs. Existing equipment will also be able to benefit from thinner electrical cables.<br />
<br />
The Falcon Ridge technology is expected to ship before the end of the year, with full implementation in 2014. The next-generation tech will be backwards compatible, using the same cables as the current tech, while the thinner cables are "coming soon."
