Mac Pro 2010 duals differences

[cube]

Are there any differences between the different dual configurations besides the chip themselves? (motherboard, heatsinks, etc.)

[jav6454]

Yes, the motherboards, RAM risers.

Where are the exact differences among the duals?

There are 8 slots on the dual socket models, but only 4 on the single socket models. Also, the heatsinks are different, its not like the singles are just missing one.

Um, I think he/she was asking if there's differences between the different duals themselves. Not dual versus single CPU.

i.e. 8-core vs 12-core

The backplane board is the same, but the CPU/memory riser cards are not. Single-CPU versions have a single CPU socket and 4 DIMM sockets. Dual-CPU versions have two CPU sockets and 8 DIMM sockets.

Exactly. I am asking about the differences among the duals, not versus single-socket.

I doubt there is anything official or confirmed as of yet but I personally doubt there is any difference. It would be too big hassle to use different parts for 8-core and 12-core while both can be made by using the same parts. We have to wait till further information. Both, 8 and 12-core even use the same B1 stepping so they will use the same EFI as well.
