USB 3.0 specs updated to boost peak bandwidth to 10Gb/s

USB-IF has announced this week that updated USB 3.0 specs have boosted peak bandwidth to 10Gb/s, ensuring the specification will now be able to compete with Thunderbolt.

The update to "SuperSpeed USB" will require new cables, but they are backward compatible with all existing USB connectors/cables.



"With the new SuperSpeed USB enhancement to increase performance up to 10Gb/s data rate, coupled with the USB power delivery specification capable of delivering up to 100 watts of power to USB-enabled devices, consumers will soon be able to have one USB cable to support all their needs," said Jeff Ravencraft, USB-IF president and COO.

The spec will still lag Thunderbolt, which can use full 10Gb/s bandwidth in both directions, using a single cable. USB 3.0 still cannot.

  Wait, so is this another new cable type, or is it the same as a standard USB 3.0 cable? Which direction goes 10Gb/s, or is it total between up/down?

  Wow thats about the same speed as HDMI cables. I wonder if that means there will be increased speeds for HDMI?
