Blackford/Greencreek (Xeon): 21.3GBs mem b/w per motherboard
G35, DDR2 Mode (Core 2)    : 12.8GBs mem b/w per motherboard
G35, DDR3 Mode (Core 2)    : 17.0GBs mem b/w per motherboard
Socket F Opteron           : 10.6GBs mem b/w per physical CPU
Socket AM2 Athlon64        : 10.6GBs mem b/w per physical CPU

Memory performance increases with CPUs in AMD platforms, decreases in
Intel platforms.

That's the incredibly naive version, anyway.
