BEIJING: THE GROUP behind the USB standard has quietly developed a specification that is set to double USB speed from 5Gbit/s to 10Gbit/s.
At the Intel Developer Conference (IDF) in Bejing, Jeff Ravencraft, president of the USB Implementers Forum (USB-IF) told The INQUIRER that the new specification is nearing completion and should be ready in June.
Ravencraft said that once the specification is complete we will have to wait another nine months before the first discrete controller becomes commercially available, and it probably will be 2015 before the new standard is integrated into chipsets.
The new standard, which has yet to be named, will require a new cable and this will be an all-in-one cable that is capable of handling the new standard as well as power delivery. The cable will also be backwards compatible with the prior versions of the USB standard.
Ravencraft also indicated that there is further headroom in the standard to again double the speed to 20Gbit/s.
The USB-IF has tightened the screws a bit on the logo standard, in that companies will only be allowed to use the logo for the new USB standard if they get their USB product(s) certified.
This doubling of the USB speed might challenge Intel's proprietary Thunderbolt technology that runs at the same speed, though it supports two lanes per port, effectively doubling the aggregate speed. µ
