The results so far show that a 16 core BD is about equal to a 12 core magny if they have the same clocks. The BD Opterons have turbo so that makes up for the crappy IPC and allows them to match the last generation chips while using more power to do it. Your two 6128 have 16 of the better last gen cores so I'm actually very surprised that your BD ship is able to come so close. There's no way you can tell how much of a difference your ram is making with such different CPUs.2. I'm surprised since this 6272 BD can't beat the 6128s. Then again, is it really a surprise?
