Intel Releases USB 3.0 Controller Interface Spec

Posted by CmdrTaco on from the lookit-all-them-wires dept.

hardsky submitted thrilling news about everyone's favorite interconnect cable by saying "USB 3.0 is set to deliver data-transfer speeds of up to 5Gb/s, initially over tweaked connectors and wiring and, later, over optical links."

  1. Do we divide 5 to 2? Or 3? by Ilgaz · · Score: 0, Flamebait

    While watching 480Mbps (!) USB 2 connected drive trying to backup at 10-12 MB/sec while my 400mbit firewire drive can hit 40MB/sec, this question popped up in my mind. "Is it up to real 5Gbps?"

    Another more important question: "What is the CPU overhead?" as I can see a wireless 811.g USB2 adapter use 40% of CPU. I notified my OS (kernel) vendor about it, they lectured me about the USB protocol and its overhead on CPU. Well deserved :)

    If there is again same trick, I wonder something. Will Intel get sued?

    They sue Microsoft (Vista capable), Apple (straches on iPod screen!) but they don't sue Intel and other members of USB gang lying to people for years.

    I don't even get into that "hot coffee" story.

    I keep seeing "480Mbps!!!" on junk devices and will buy 120 meters of CAT5 cable because my Mac Mini dies because of USB2 811.g dongle's 40% CPU overhead. Same Mini G4 does 40MB/sec on a Firewire 400 drive without any CPU usage.

    Lets hope Firewire guys ship the promised 1600/3200 stuff soon. I opt in for real 3200 mbit rather than "therotical" 5 gigabit, thank you :)
