You’re welcome

I’m no industry analyst, just an enthusiast when it comes to small-form-factor systems and consumer processors/chipsets.
[oops, looks like I ended up writing a wall of text again...]
Concerning hw upgrade flexibility, owner’s tendency to replace parts of a system has an inverse proportion to age (both)
, for example why did you buy a totally new setup for CUDA, why could you not just upgrade?
To go slightly off-topic, I would have upgraded a setup for CUDA... if I had an existing system to upgrade. The family desktop was an old socket-478 Pentium 4 with AGP+PCI. So the CUDA rig is effectively my first self-assembled desktop xD (yeah, I was really late to the self-assembled PC game...)
The family desktop is now an E5300 Pentium dual-core on Intel G41 chipset (socket 478 was at the end of its upgrade life, so I gave it away to someone upgrading from a Pentium 3). They don’t need anything powerful, so they’re happy with it. In the near future I can still upgrade it to a Core 2 Duo/Quad without having to change the chipset, which is really convenient (and wallet-saving).
I am largely vendor-agnostic, and while I still am hankering for an Intel Lynnfield desktop, my CUDA rig is an AMD Phenom II. So while I do not hold any grudge against Intel for their unfair pricing practices, I’m not an Intel-exclusive person either.
At this moment it really irks me that I have to shell out:
$170 for a
Zotac board with Nvidia ION+Atom N330($190 for
a variant with integrated DC-DC power supply + AC-DC adapter)
$130 for a
Zotac board with Nvidia GF9300 and LGA-775 socket (with rebate).
If you look at the
Intel Atom N330+945GC boards you’ll see just how cheap Atom N330 systems can really be.
Without knowing the industry that well, and without insider information I won’t attribute ION’s high cost solely to Intel. Perhaps Nvidia just isn’t that good at marketing or cost-reduction, who knows?) But when such news is released, one has to wonder if things really can’t be any cheaper than they are. Assuming what Nvidia’s CEO said about the cost of Atom processors is true, how much cheaper can we get ION systems? Even a 10% reduction in overall price is sizeable.
A small form-factor platform with decent HD playback performance under $150 (sans casing, peripherals etc) suddenly sounds very real. What would it take to get us there? Maybe Intel can stop pricing Atom so high for third-party developers. Maybe Zotac can think about improving production efficiency. And maybe Nvidia can actively work towards getting things sorted out with Intel. Who really knows how these things go. All I know is,

An HD-capable setup like that could one day be available for less than $400.
Fine, not terribly exciting news for most people >_> especially when
Best Buy already has HD-capable dual-core systems for <$400, but for small form-factor enthusiasts, ION is a big step forward, both in terms of price and performance.

And to try to get back on topic now, I have to admit that I’m not really feeling the pinch from Nvidia losing the license for the new DMI bus, despite all my ranting. The PCI-e hub and memory controller are on the Lynnfield die now (Intel calls it the
uncore, to separate it from the processor), so the P55 chipset is nothing more than an overpriced, glorified “ICH10.5R” southbridge.
Even so, the ICH10 is an
excellent southbridge, and I find it unlikely that Nvidia can make a southbridge that will blow the ICH10 away performance-wise.
Besides, now that the interconnect (link between chips) is reduced to
DMI with 1GB/s bidirectional transfer rate (you’ll see this written as 2GB/s, which is just total up+down transfer rate), Nvidia loses a big part of their advantage. Their nForce chipset used HyperTransport for the chipset interconnect, giving their southbridge a
maximum transfer rate of 8GB/s, about 4 times more than DMI. That’s an advantage gone if they’re going to start making DMI chipsets for the new Nehalem. (Nvidia has already announced that
they will not be making system chipsets for Bloomfield, i.e. socket-1366 Core i7.)
Still, it would be great if Nvidia can make an alternative product, even if it’s just to compete with the
horribly overpriced P55 chipset ($40 for P55 vs $3 for ICH10R, to serve the same function). Anything to make Lynnfield ownership cheaper ^^
