AMD's competitive technology to Intel Thunderbolt, called "Lightning Bolt" (codename, marketing name may differ), surfaced at CES, where AMD was showing off its upcoming "Trinity" accelerated processing units. The technology was dissected by Anandtech, revealing exactly how AMD plans to achieve its goal of providing a much lower-cost alternative to Thunderbolt, over a similar-looking interface. While Thunderbolt is essentially PCI-Express x4 over DisplayPort, Lightning Bolt is the much more mature USB 3.0 SuperSpeed over DisplayPort. It is a single cable that combines a USB 3.0 with DisplayPort (display), and power (sourced directly from the PSU).

That's a really weird approach.. What advantage could it offer over just using the standard USB3 port? :shadedshu

Yeah...? AMD, I hope you just hired a new PR department to make this look good. Otherwise, I'm failing to see the point at this time.

While the competing Thunderbolt also doesn't impress me, I think being based on PCIe would have advantages worth the cost such as device connection, slot expanders, and latency. This last item I need to research, get some hard numbers for comparison.

Apple's original plastic Cinema Displays did something similar ten years ago with a single cable from display to tower carrying power, video and USB. They called it Apple Display Connector and it was nice (especially from my IT perspective) provided you had all compatible gear. Especially coming from gigantic CRTs plus secondary smaller flat panels and all the associated cabling and adapters (what a nightmare to set up and break down which I had to do often). The next iteration of the Cinema Displays moved on to standard DVI, however.

It uses Display Port signalling (21.6 Gbit/s). Hence it is faster than USB 3.0.

ya but whenever apple tries to do that its just to get patents for it and monopolize the tech, basically meaning only apple can make it... Just shows how popular Apple is to the computer community, which is very nill. I wont own an apple product. Its just like how USB is more popular than firewire

Actually, it doesn't. If you read the story over at Anandtech you'll see that Lightning Bolt is actually slower, so this is utterly pointless if you're after something that offer fast data transfer speeds.

I hope your ;) means you're not serious. So, I am now to buy a keystick, a mouse, phone, and a camera that has a secondary "daisy chain" port? Methinksnot!

So, to avoid thunderbolt license fees (or less than a $) we now substitute those fees for USB3.0?

AMD is solving a problem that is already solved. Let it die, like HDDVD, minidisc and betamax.

Think about several Daisy Chained drives in RAID. Does it make sense now ?

Thunderbolt does everything with one standard including looking forward at fiber optic. This is three standards duct taped together. DisplayPort uses a different packet standard than USB and USB uses 5V where most monitors and the like would like at least 12V. From the sounds of it, they're talking two data packets and two power lines in one cable. That's not innovative; that's fumbling.

I think there is a market for power and data inside the same cable for monitors if only for power efficiency sake (computer PSUs are often far superior to those found in those little bricks LCD monitors use). I just can't see this as being the answer.

Also Thunderbolt is good because it delivers awesome speeds (20Gbps) and PCIe compatibility for external GPUs.
Isn't USB 3.0 max speed 5 Gbps? Daisy chaining devices would bottleneck you faster than Thunderbolt unless you attach multiple USB 3.0 controllers (I honestly don't know if this is possible)

Of course we're all going to take your word that Anand is in Intel's pocket, since you're the one running one of the most trusted computer hardware websites that's been around for over a decade. OH WAIT.

If you think that it is slower than USB 3.0, wait and see;).
All I see is AMD trying to steal some of Intel's thunder, as usual - by introducing something shitty and un-innovative, as usual. I'll start believing AMD hype when they start delivering non-sucky hardware that isn't graphics cards.

I'm pretty sure they're going to introduce docking stations with additional features for Ultrabooks like the Apple Cinema Display with Thunderbolt that adds connectivity to the Macbook Air
I'm confident that this will make a nifty solution for who doesn't need a full blown desktop but can surely enjoy something similar when at home while keeping an ultra portable device like Ultrabooks :)

It would be nice if you and all the other people spreading this FUD would learn the real facts. To wit: Intel is the one who created the actual Thunderbolt specification and they own it and allow anyone to use it royalty-free. Apple originally registered the "Thunderbolt" trademark, but Intel now owns that mark.
