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.

quote: Why not utilize the CPU more ? There is so much potential we're not even exploring. This is a good thing Intel is doing !
quote: It is my understanding that Firewire is a lot less processor intensive.
quote: 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.
