New standard relies on smarter controller chip to offer optimized 20 Gbps bi-directional flow
show in Taipei, Taiwan Intel Corp. (
its next generation successor
to Thunderbolt, Thunderbolt 2.
Released in 2011, the original Thunderbolt
was championed by Apple
, Inc. (
). Many derided its
expensive proprietary cables
and the lack of peripherals. But on paper the technology impressed with four uni-directional 10 Gigabits-per-second (Gbps) channels.
Today there's many
more compatible devices
(roughly 80 by Intel's reckoning) and cable prices have begun to relax. At the same time adoption among Windows personal computer makers has begun to heat up, thanks to roughly 30 compatible motherboards.
That's where Thunderbolt 2 comes enters the fray.
Scheduled to land before the end of 2013, with a ramp up in 2014, the second generation technology uses a new controller chip to merge the uni-directional channels into two 20 Gbps bi-directional channels. This will allow faster speeds when driving data primarily in a single direction (e.g. when copying files to a backup hard drive, etc.).
The good news for consumers is that owners of current generation Thunderbolt cables will be able to reuse them -- the cable design remains unchanged.
Intel says that the new standard, previously codenamed "Falcon Ridge" will be useful in transferring
from devices. Currently transferring this resolution's massive files is a relatively slow and onerous process, depending on the video length.

RE: What can transfer at these speeds?

I agree that they do not compete, however many consumers and peripheral makers don't see it the same way. USB Bus powered hard drives are commonplace in the consumer market, even though USB is poorly suited to both bus-powering a hard drive, and poorly suited to bulk data transfer. The reality is there is consumer market overlap between the USB and Thunderbolt.

The new USB3 10Gbit/s is getting more power also. I don't recall how much, but it was improved for sure.
