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.

A10K 100W of power through a single cableReply
100W/5V = 20A of current through a single connector.
???
Does this sound fishy to anyone else? Maybe an extra 0 in there somewhere? -

That does sound very high. -

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. -
DRosencraft 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).Reply -
azgard 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.Reply -
sundragon The cable's gonna have to be thick to provide that kind of power...Reply
