Mockup USB 3.0 cable  (Source: Tech On)
Intel says open host controller specifications have cost gazillions of dollars to develop

According to Intel’s Nick Knupffer, there are a lot of myths going around concerning USB 3.0 and Intel’s involvement in the development of the specification. Knupffer wrote a blog post on Intel’s website in an attempt to dispel these myths.

Knupffer points out that Intel is not developing the USB 3.0 specification. What Intel is developing is the host controller spec which Knupffer describes as a “Dummies Guide” to building a USB 3.0 compatible piece of silicon.

Knupffer says in the blog post that Intel has invested “gazillions of dollars and bazillions of engineering man hours” in developing the open host controller and despite its significant investment still plans to give the specification to competing manufacturers for free. Knupffer also says that Intel loves it when CPU performance is used to the max and the huge increase in bandwidth of USB 3.0 will mean larger file transfers and more processor usage. This in turn is expected to lead to an increased demand for faster processors.

AMD and NVIDIA leveled allegations at Intel recently that claim Intel was withholding the open host controller specifications in an attempt to give itself a market advantage. Intel and AMD claim that by withholding the specification the lead Intel will have in bringing USB 3.0 compliant products to market will be in the six to nine month range.

Intel denied the allegations of withholding the open host controller specifications at the time AMD and NVIDIA made their charges public and announced they would be designing their own open host controller. In Knupffer’s blog post, he again says that Intel isn’t holding the open host controller specifications back from competitors.

According to Knupffer, the significant investment in the open host controller specifications is specifically to get USB 3.0 into the market faster, so why would it withhold the specification. Intel still maintains that the specifications aren’t ready and that it plans to give the specifications to other manufacturers in the second half of 2008.

The final myth that Knupffer addresses in his post is that USB 3.0 technology borrows heavily from technology used in PCI Express. Intel points out that it was involved with both the PCI-SIG and the USB-IF at the design stage for both PCI Express and for USB 3.0. The insinuation form Intel is that the technology that is similar in both devices was developed on its dime.

The problem with now compared to the USB 1.0/1.1 days is that there are multiple manufacturers for processors, chipsets and motherboards so Intel should not be the only one working on the logic and coding for the USB 3.0 spec. they should work with AMD, nvidia, VIA as well as the motherboard manufacturers to make sure everyone is on the same page and ends up with hardware and BIOS revisions that can take advantage of the higher speeds.
By Intel not allowing others to help work on it, you know that Intel will release it first with their chipsets and that will give them at least a 6-9 month head start over everyone else. This is exactly what Intel is working towards.

You belong in the news. You took what someone else already said, and then restated it as if it was your original thought.

I am a tech journalist so I guess I just re-worded what others have said... but I still posted this because I agree with it.

Yea if they weren't calling it an Open Host than they could do that.

Some people miss this entirely. AMD and Intel have a cross licensing agreement. If this was like the stupid game company that bought the UT3 engine it would be one thing, but intel has taken an open tech said they would come up with the controller "dummy guide"(so that everyone is compatible) all the while developing hardware for it, holding the the early drafts AMD and Nvidia (not to mention Via and SIIG) preventing them being able to developing the parts at the same time as Intel. If its open technology why should Intel be allowed to get a 6 month headstart, and along with that why would AMD/Nvidia be looked down apon for coming up with their own compatible* USB controller.

Intel knows that without this "dummy guide" that even within the USB specs their will be enough differences between the two crate incompatibilities. This is what you call Anti-competitive behavior. They had to pay $250 million to a Texas based computer Manufacturer (insperion?) for the same type of information hold back, because while they used Intel CPU's (pentium pro), they used homegrown and serverworks chipsets on their homemade mobo's for their workstation and servers.

You're missing a key factor, that they could still release the current information without the spec done so that the other companies can put forth the groundwork for their own implementations, having most of it done even if Intel changes some things they then have to change themselves.

Their claim is correct, if Intel doesn't release the spec or key details far enough in advance it will give Intel a market advantage. Perhaps in a perfect world Intel would be entitled to this advantage for their money spent, but that's not the rules under which the game is being played.
