I suppose that AMD's result was obtained on dual-cpu platform, so actually there were 24 threads, not 12. Also Core i9 is not a competitor to Magny Cours since i9 is a desktop CPU and probably will at least twice cheaper then a cheapest Magny Cours (without considering matherboard prices). Nehalem-EX (8 cores, 4 channel mem, 24MB L3) is a direct competitor of Magny Cours.
Still new AMD platform has very good bandwidth per socket with its 4 mem channels.
