This great speculation comes from Intel telling the media that it will “host a press briefing to discuss a new technology that is about to appear on the market.” CNET apparently has “an industry source familiar with details of the event” and says that it will indeed be Light Peak. Other speculation surrounding this news is concerning whether or not this launch will have anything to do with the new MacBook Pros also set to be launched on Thursday.
Rumors have been circulating since late 2010 about Apple possibly incorporating Light Peak into its 2011 MacBook Pro models. Since then, there have been leaked spec sheets floating around as well as product photos of a 13-inch MacBook Pro which would back up this rumor if it is true. If this is true, then Apple plans on renaming it “Thunderbolt”. However, it is unclear whether or not Intel will adopt this nomenclature as well.
Whether you decide to call it Thunderbolt or Light Peak is up to you, but know that it is a single interface designed to replace the SCSI, SATA, USB, FireWire and PCI Express ports on a computer. The technology, which is copper-based, supposedly delivers 10Gbps bi-directional data transfers and is the main reason some people have speculated Intel has been so slow to adopt native USB 3.0 support on its motherboards, something Intel has not surprisingly refuted.
