AMD and NVIDIA say Intel won't share its USB 3.0 open host controller specs

The USB 3.0 specification is expected to be out in 2009 and will significantly upgrade the bandwidth of the current USB 2.0 ports and products that all computer users are familiar with. The body responsible for the support and promotion of the USB specifications going back to USB 1.1 is the USB Implementers Forum (USB-IF).

The USB-IF was founded by Intel in 1995 along with other industry players including Microsoft, HP, Texas Instruments, NEC and NXP Semiconductors. Currently, the USB-IF and its members are working to bring the USB 3.0 specification to market. USB 3.0 is also being called “PCI Express over cable” because the USB 3.0 specification uses intellectual property that was sourced from the PCI SIG. USB 3.0 will increase the bandwidth offered by USB 2.0 by 10 times with a data throughput of about 5 gigabits per second.

Despite the fact that much of the intellectual property behind the USB 3.0 specification wasn’t developed by Intel, AMD and NVIDIA both assert that Intel is keeping crucial information concerning the open host controller to itself. According to NVIDIA and AMD, Intel has working silicon, meaning the open host controller portion is mature and working, yet Intel is refusing to give the specifications to other processor and chipset makers.

AMD and NVIDIA say that by withholding the open host controller specifications that Intel is basically giving itself a market advantage of six to nine months because of the time lag between receiving the host controller specifications by other CPU and chipset makers and getting product to the marketplace.

An Intel source told, “Intel only gives it [open host controller specifications] out once it's finished. And it's not finished. If it was mature enough to release, it would be released. If you have an incomplete spec and give it out to people, these people will build their chipsets and you'll end up with chipsets that are incompatible with devices. That's what (Intel) is trying to avoid."

The Intel source continued saying, “[Intel is] a little bit behind and that's what might be causing some of the resentment. You could take the opinion that Intel is giving stuff out for free and people are complaining because (Intel) isn't giving it out fast enough.”

If Intel feels that AMD and NVIDIA aren’t willing to do the hard work of developing the open host controller for USB 3.0 themselves, it may be very mistaken. AMD and NVIDIA say they are going to develop their own open host controller for USB 3.0. Both firms point out that developing a separate open host controller could very well mean incompatibilities between USB 3.0 controllers and products.

An AMD source told, “We are starting development on it [open host controller] right now.” An NVIDIA source says the first meeting of the alternate open host controller specification is set for next week and adds, "We fully intend to productize this spec.”

Intel maintains that it is not withholding the specification and that it will provide the details for the open host controller when it is complete.

Intel is in hot water already for some of its business practices. The FTC announced last week that it will investigate whether Intel has abused its market position to stifle competition.

Itanic was a failure since day 1... we didn't need Windows X64 to know that, no one expected a far inferior product in real world tasks to now change all our habits, Intel just learned the hard way that people don't like changes.

here is a completely different matter, Intel is part of the USB-IF and a big part of it, do you really think some outsiders that don't even are the major players on the OEM market would have enough power to shift it towards them rather than to Intel? Besides as I read it Intel would release its product at the same time as them, and NEC, HP and TI are other key players that will use the same specs as Intel.

No it wasn't, in fact i remember when it was a hotly anticpipated product and I also remember a lot of industry buzz about getting rid of the complicated x86 instruction set finally (many thought the wrong side won in risc v. cisc), there were a lot of factors involved in the demise of itanic, but the fact is x64 made the failure inevitable, when otherwise it may well have been a long term success which is what Intel had been planning since day one.

Anyway, back on topic... AMD and nVidia are much better off developing their host controller together. You can either have 2 seperate host controllers that are potientially incompatiable with eachother, or you can have 3 leaving AMD and nVidia on their own to abosorbe the impact of the broken controller. At least together they can share the burden which is a great thing for both companies, as neither has intel's resources to deal with USB implementation issues and all the products they actually *WANT* to be developing.

Seems like I said a few weeks ago, any partnership between nvidia and amd that they maintain or develope new will benefit both companies. I guess we'll just have to watch and see.
