Does anybody know about it? Are the new G5 soldered onto the motherboard or do they use a daughtercard solution for this? It would be an important detail, you could upgrade a single G5 machine to a dual to enhance performance.

You can't upgrade a single g5 to a dual g5.
And it's hopefully on a daughtercard.

So I guess it means they have a few different motherboard designs then. Where did you read this?
You can downgrade a dual G5 to a single G5 though. They did this in the VeriTest benchmarks.

They probably just did that in software.

What Eug said: That would mean there is a single proc. motherboard version and a dual motherboard version. Kinda unlikely!?!!!
And what about future upgrade kits from Newertech and Sonnet? IIRC you can plug in a dual daughtercard into a former single proc. machine.

No they physically removed the processor.

I would think that because of the Unshared bus for memory, either the mobo is for duals or it is not.
Thus, no processor pack swapping.
The better question is "Is the G5 processor card upgradeable?" so when the 3GHz ones come out in a year, you can replace your 1.6 or dual 2.0 with a 3.0 or dual 3.0, etc.

Why would that be a problem? The system controller could detect if the second processor bus is in use and if not simply shut it of. Big Xeon Workstations can also run with one or two processors (but i do not know if they work with shared or unshared bus).

I can dis- or en-able the L2/L3 cache or the number of CPU on my FW800 via the Apple's CHUD software [ available at their developer site].

It's not a "problem", but Apple, who is very cost conscious, would likely not place the controller or the ram slots for a processor that the machine didn't ship with.
It's possible that there is only one mobo for both the dual and the single G5 with PCI-X (I am ignoring the 1.6GHZ Yikes model), but I seriously doubt all the components are there for a dual on a single processor machine.
Until proven otherwise, I stand by my supposition.
