Chip designer AMD is working on Lightning Bolt, a competitor for Intel's Thunderbolt technology. The Lightning Bolt platform will not go after the same high-bandwidth market as Thunderbolt, instead its focus will be on multi-device and electric charging capabilities.
Plugging a Lightning Bolt enabled cable in a single DisplayPort 1.2 port will enable you to connect to a dock that can drive up to three additional displays, as many USB ports as you want, gigabit Ethernet, audio ports, and even recharge your laptop.
Interestingly, Lightning Bolt is a hardware capability that doesn't require drivers. It enables USB 3.0 channels from the chipset and the DisplayPort channels from the APU to be routed over a cable and out to a hub. Basically, AMD promises a wider array of connectivity capabilities than USB 3.0 and Thunderbolt at a cheaper cost. More info can be found at SemiAccurate.
