Thunderbolt controllers to 20 Gbit/s in 2014?

By , source: Digitimes

A road map from earlier this year already revealed Intel's plans for this year and the next with regard to its Thunderbolt technology. At the time, it was unclear what 2014 would have in store for us. Digitimes now claims that the first 20 Gbit/s Thunderbolt chips are due that year.

The current Cactus Ridge, and next year's Redwood Ridge controllers, will be limited to speeds of up to 10 Gbit/s. Intel has always claimed that the technology is capable of reaching much higher speeds of up to 50 Gbit/s when using optical cabling. It will take another two years before we can benefit from the increased bandwidth, as Falcon Ridge will release in 2014. It's expected to be a 2-channel controller, offering a relatively high bandwidth per channel and making it exceptionally suited for daisy chaining multiple devices.

According to the latest reports, the Redwood Ridge chips, planned for next year, will release simultaneously with the Haswell platform. New features compared to the current generation include support for DisplayPort 1.1a and DisplayPort 1.2 Redriver standards. The latter describes a technique which amplifies the data signal, allowing it to be sent over greater distances.

For now, it is unknown what Intel has planned beyond 2014, but it will undoubtedly involve greater speeds and lower controller prices.
