Clash of the Titans Over USB 3.0 Specification Process

Ian Lamont writes "Nvidia and other chip designers are accusing Intel of 'illegally restraining trade' in a dispute over the USB 3.0 specification. The dispute has prompted Nvidia, AMD, Via, and SiS to establish a rival standard for the USB 3.0 host controller. An Intel spokesman denies the company is making the USB specification, or that USB 3.0 'borrows technology heavily' from the PCI Special Interests group. He does, however, say that Intel won't release an unfinished Intel host controller spec until it's ready, as it would lead to incompatible hardware."

      Firewire is not designed to run peripherals. It's designed for high speed, efficient transfer of data. The closest it gets to peripherals is high end scanners. Mice, printers, keyboards, basically anything human interface is more appropriate for USB. Universal Serial Bus. Firewire is not universal. The overhead created by being universal makes even the high speed USB (480) transfer data slower than Firewire 400. Then there's Firewire 800 which leaves USB in the dust nicely on file transfers.

      Also firewire IO is done on the card/chip, whereas USB is done to a large degree by the CPU. This is why we saw recent threads about the 'security risk' associated with jacking into the firewire port of a computer - you have direct access to system memory on most systems. Try a file copy with USB 2, and again with firewire, watch your processor. BIG difference. This is important when you are processing video, you can't have your video IO making your video processing lag and skip frames. That's one of the reasons firewire remains dominant on video.

      The only aspect of this I find puzzling is the scarcity and cost of firewire flash drives. kanguru makes them but they cost 3-4x as much as comparable USB thumb drives. Best guess here is thumb drives started their boon before most PCs had firewire ports, so they were just trying to hit the largest market, which lacked firewire, and so now we're stuck with it.

      Ethernet is good, but it does not support isochronous transfer.

      Of course not. But be honest. How often is that a critical requirement? Like I said, Firewire has been relegated

      With Firewire, isochronous mode creates dedicated timeslots for devices that produce steady streams of data. DV and DCAM camera interfaces, multiple ADAC audio interfaces, you can theoretically load the bus to very close to 400MBit, and never have to worry about collisions or jitter, indeterminism, latency, or packet loss.

      Firewire may be able to guarantee 400Mbit/s, but that's not much of an advantage when Ethernet can provide nearly 1000Mbit/s.

      Jitter, packet loss, et al., are non-sequiters. They are already handled appropriately and reliably. Collisions are a thing of the past, you can't even find gigabit hubs.

      Latency/isochronous transfer is an issue to ONLY a small bit of studio equipment... Which is where Firewire has been relegated to. And with such a small niche, it may go out of fashion there in short order, as other protocols that have better penetration get slightly expanded to eat away at that niche. eg. HDMI, SDI, Fibre Channel, iSCSI, etc.

      DV cameras could benefit greatly from the faster-than-realtime transfer that ethernet offers and seem likely to switch away from Firewire in the near future. Eliminating the fixed-data rate realtime transfer would also allow for the use of much better (VBR) compression, with the potential for higher capacity on the same media, and longer battery life as well.

    I'm sorry but I disagree with just about everything you said:

    - all things being equal, USB-Intel would lose, look at the companies opposing it, you have AMD, Intel's biggest rival in chipsets, you have nVidia, the biggest gfx company, you have VIA and SiS - who handle pretty much every other chip in your computer.

    In short, every chip in your computer except your intel chip would be specced to the disputing standard, what would Intel do to counter that? Personally try to take over the gfx market, the VIA market (I say that because it pretty much is VIA's monopoly)?

    Don't get me wrong, Intel is powerful - but they haven't been the 5000 pound gorilla in a couple decades. I mean, Microsoft rose against Intel - that was decades ago. If you talk to most casual gamers nowadays I'd say they're more likely to recognize nVidia than Intel.

    It's pretty much impossible for Intel to pull what you suggest off, if nVidia and AMD/ATi oppose them together that would kill off Intel in pretty much any non-linux computer. I mean, granted Intel does like linux, but I don't think they're willing to suicide their MS market over a USB standard.

    Also, saying there is no significant use for speeds above 2.0 is retarded, I'm sorry because I don't want to resort to personal attacks - but seriously - 2.0 isn't very fast in all honesty, to think that 2.0 is where tech is going to level off is (again) retarded.

    The upshot is that when you actually use one bus or the other to, say copy files, firewire at a mere 400Mbps trounces USB2 in throughput.

    Yes USB3 is in the pipe with vastly improved on paper specs, but then again Firewire has 3200 and 6400 variants in the pipe as well.

    Essentially USB should have been left as an interface for keyboards and mice, and firewire aught to have been adopted by intel as the preferred bus for all high throughput applications, it would also have been preferable to SATA.

Adding USB to peripherals is almost free.
