Intel seen planning Thunderbolt dock standard for ultrabooks

Intel proposes Thunderbolt dock connector

Intel is hoping to formalize a standard for docking on ultrabooks with Thunderbolt ports, leaked internal notes demonstrate. The implementation would combine the Thunderbolt port with a wider companion dock connector to handle other forms of data, such as Ethernet or USB, VR-Zone said. To keep the Ethernet connection alive for Intel's vPro remote management or for Windows 8's Connected Standby mode, however, the docking port would need to have direct access to the Ethernet chipset inside.

The chip designer also had suggestions for what the dock itself could have, including HDMI or Mini DisplayPort for video out, a USB hub, or even eSATA for fast external drives. Thunderbolt's support for daisy chaining a total of six Thudnerbolt devices is an option, although it would require the widest bandwidth versions of Thunderbolt and may be rare.

Intel's strategy would be primarily intended for business, where it's expected that workers would dock the ultrabook at their desks and get an external display and desktop-like expansion with just one cable. It notably tries to downplay the use of USB 3.0, saying that the standard isn't ideal for displays or certain kinds of links. Intel might have an economic incentive to discourage USB 3.0, however, since it can profit from its exclusivity on Thunderbolt controller chips where USB 3.0 is generic and won't see Intel make much if any profit, even when its own hardware is in use.

Apple already has a form of Thunderbolt docking through its Thunderbolt Display and may end up having the superior option for simplicity: its lack of vPro lets it route audio, the display, Ethernet, FireWire, and USB through one cable. Intel's approach would bring more of that experience to Windows users as well as provide some extras for the pro audience. Non-Mac systems with standard Thunderbolt aren't due to show until at least early 2012, however, or roughly a year after Apple went first.

    Ethernet connector

    Hopefully, Intel or someone will come up with a replacement for the oversized and difficult to disconnect Ethernet connector. I tried to get Apple to do something like MagSafe but go nowhere.
