Nice... too bad all of our cabling is Cat5.

While the world pushes tighter integration, who does TI think is going to pile
on to a proprietary way to split a system into chunks?

I love the bit about remoting HID devices.
Yeah, there's a high-throughput market to exploit...

Well, I'm sure the motherboard makers will provide you with some Cat6 to
connect your PCI-E devices remotely with. :-)

Maybe it's for the really, really, really fast typers? :-)

I guess in their haste to get a press release out they forgot that this sort
of job is already done by USB?

I'm sure they have much more important ideas in mind behind it, but none of
which really excite nor matter to typical home users. Things like clustering
interconnects or remote storage devices.

As I said, maybe they have some really big ideas, they just weren't smart
enough to make it sound exciting on a press release. :-)

Maybe we could one day get little modules with just the CPU and Gig-Ethernet
port to Add extra processing power.

What can be used to take apart can also be used to put together. What
TI has done seems like some version of I/O that Intel was pushing...only
it's not Intel silicon, just like Infiniband isn't Intel silicon. How
will Intel react to this one: cut loose PCI-Express?

I've crossposted to comp.arch to see if I can't attract comments about
how real this is and what effects if might have outside the Intel/PC
marketplace.

They are sending a 1X pci express over 4 pairs of CAT6 which is better than
CAT5 which 1000baseT uses.
They don't say how long the cable is. Ethernet uses 50 to 100 meters. 2-5
meters is a lot easier.
PCI-express is 2.5 Gb/s on the wire, GigE is 1.250 on the wire,
PCI express is working on cabling extensions. Intel is big on it. Why
would this make them upset?
1X PCI express is equivilent, roughly, to the 66MHz 32 bit PCI slot. Or
maybe to a 66 by 64 due to being duplex.
Many folks don't like to open the box to add stuff to their computer. This
is an alternative to things like firewire and USB2 as a way to add stuff.

I probably should learn not to make remarks like that. Fat chance. ;-).

Since it's _TI_ silicon first to market, it would seem to have the
potential to interfere with IBM's plans to take over the server room
starting at the processor and moving outward.

I dunno. I know even less about expansion bus protocols than I do about
most other things. Is there anything you can do with any available
out-of-the box interconnect that you can't do with lower latency using
PCI-Express? Limited bandwidth and distance, to be sure, but how could
you beat the latency?

IB and PCI-Express should be pretty comparable. (PCI express isn't out of
the box yet)
Ethernet with RDMA and hardware offload is in the same ballpark.
Rapid I/O, Fibre Channel, are contenders depending on task.

Is latency a big deal writing to a disk or graphics card?
