AMD's Bobcat and Bulldozer

[informal]

gallag, I usually don't bother reading anything you post,it's just a waste of time .Paranoia level is high,i will give you that.

right that's what I thought, because otherwise we would be seeing zero increase from core 2 to sandy bridge as primarily only the logic and prefetchers were changed

There were many core level changes ,especially in the prefetch area,one of the weaker points of 10h cores.
