SuperSpeed USB to Provide 10 Gb/s and 100 W

Recent updates to the SuperSpeed USB specification seeks to offer data throughput performance of 10 Gbps and power delivery of up to 100 W.

Speaking at this year's Intel Developer Forum (IDF) in Beijing, the USB Implementers Forum (USB-IF) announced that they are currently developing a new specification for SuperSpeed USB that will "recognize consumer demand for a simplified single-cable solution to power and simultaneously transfer data to their laptops, tablets and smartphones.”

This new specification aims to double the data through-put performance of USB 3.0 to 10 Gb/s and incorporate the new USB Power Delivery specification that is capable of delivering up to 100 W of power through a single cable.

“USB continues to anticipate consumer need with relevant capabilities and increased speeds, including the new SuperSpeed USB at 10 Gbps transfer rate and Power Delivery specifications,” said Greg Potter, Analyst, Multimedia Research Group. “The delivery of USB 3.0 certified products is continuing to grow exponentially, with over 1 billion USB 3.0 products shipping by the end of 2013. This huge growth is a testament to the benefits, ease of use, and continued relevance of USB technology. Industry adoption will only expand as USB continues to be the standard to which all other I/O connections are compared.”

The new SuperSpeed USB specification will be finalized by June with the requisite hardware controllers available within the next nine months. Additionally, in an interview with The Inquirer, Jeff Ravencraft (USB-IF President) added that there "is further headroom in the standard to again double the speed to 20Gbit/s" which would bring USB's speeds on par with Intel's next generation Thunderbolt specification.

The USB-IF and its member companies are currently showcasing their latest developments during IDF 2013 being held from April 10 through April 11, 2013 in Beijing.

    100W of power through a single cable
    100W/5V = 20A of current through a single connector.
    ???
    Does this sound fishy to anyone else? Maybe an extra 0 in there somewhere?

    Need to do something considering what Thunderbolt can do.

    That does sound very high.

    12 gauge wire all the way :) 

    Maybe the will just go for a higher voltage(12) and call off backwards compatibility but still 8.3 amps is a good bit too.

    you can probably power a smaller card like a 7770 externally at that rate

    I guess they saw enough threat from Thunderbolt to step up their game a bit. But still, I don't think it's needed right now - nice to have to look forward to. It makes more sense than Thunderbolt does right now since USB already exists as a standard, so this would likely see success that Thunderbolt doesn't because of being a new connection standard. At that bandwidth and power delivery, you could possibly run a monitor off that single cable (provided they include it as a connection on a GPU and you've got a PSU big enough).

    Increased power budget is nice and all, but 100w? And good luck with the marketing nightmare that's going to ensue with cables that can't support that, let alone devices standard laptops almost everyone buys is lucky if the -brick- is even rated to supply that much power. They should have migrated to a 12v supply or at least provision it when they first rolled out usb 3.0 little late now.

    The cable's gonna have to be thick to provide that kind of power...

    As far as I know even 1 A can be very dangerous for a human. You must also consider wire thickness to supply that about of current. It may have use is specific situations. Everything does not have to consumer oriented.

    why would one need 100w on a USB port? That is 20A at 5v or ~8A at 12v.

    Not at the low voltages used in computers.

    First, super speed is a dumb name.... Second, if they already know they have the headroom for 20Gbps... why not work on that instead of going to 10Gbps first... then just call it USB 4.0 and be done.

    tha salot of amps for a single cable >_< either the cables are going to be expensive or tey are going to be super thick... probably both.. also somebody can correc tme if i am wrong but i though lithium ion batteries were limited on how much power you can charge em without doing damage.so either batteries need to evolve or the extra power will only be useful for things like extrnal praphics card (which is pretty cool but nto thinking there is a large market for it let laone one to make it a standard feature)

    Powering usb controlled Christmas lights? :p 

    On a serious note, I can only think of 2 things (for now) of the benefits of having that much power running though a usb cable.

    1. Cable Management. Having power and data running over 1 cable instead of 2 for your accessories such as printers,(Probably more useful for commercial/educational places than a consumer home).

    2. Supporting very large daisy chains of usb devices without using a powered hub.

    I cant see this USB tech upgrade going anywhere, unless the cables are $100 each.
