USB 3.0 may not arrive at the same transfer rates as the Thunderbolt interface, but in terms of power offered for devices, a new standard specification promises to leave Intel's technology behind.
In a new document (PDF) published this week, the USB 3.0 Promoter Group announced that this specification will have a power of up to 100W (the current one does not exceed 5-10W, as well as Thunderbolt), enough to power a series of peripherals that nowadays depend on external power sources including even monitors.
The USB 3.0 Promoter Group stated that the new standard will begin to be evaluated by the industry at the end of the year, and can be released to manufacturers through the USB Implementers Forum (USB-IF) as early as 2012. It will be backwards compatible with the current SuperSpeed ??and including with USB 2.0.
