New standard relies on smarter controller chip to offer optimized 20 Gbps bi-directional flow

At the 2013 Computex show in Taipei, Taiwan Intel Corp. (INTCunveiled its next generation successor to Thunderbolt, Thunderbolt 2.

Released in 2011, the original Thunderbolt was championed by Apple, Inc. (AAPL).  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 4K video from devices.  Currently transferring this resolution's massive files is a relatively slow and onerous process, depending on the video length.

Human Centipede style?? Gross, lol.

But yeah, SCSI and Firewire shared that same advantage over IDE and USB in their heyday.

Not to mention that Thunderbolt can be used for video displays, which have a high bandwidth requirement. One 1080p60 display needs ~4.5 Gb/s.

I'm an AMD fanboy myself, but I'm very interested in this Technology. This could be the next "multi port" like USB is today. Serial? Gone! LPT/Parallel? Gone! PS2? Gone!

Next? USB? Firewire? VGA? DVI? HDMI? Esata? Proprietary Tablet cables (Samsung, ASUS)? Thunderbolt 2 possibly Trumps it all. Why have 3 or 4 different port types when all you need is 1 and it daisy chains?!

Heck, can we make this the new power cable?! They were experimenting with making USB3/4 just that.

As long as this doesn't have direct and unwarranted access to the RAM like firewire (BIG NO-NO!) I'm totally game!
