I remember when I upgraded from athlon x2 5000@3.1ghz to phenom 9600@2.3ghz. I could not OC phenom as I had crappy motherboard with some crappy ram. And everyone considered K10 launch a disaster. BUT that phenom was pulling better or equal numbers in all the apps I was using which where single or dual threaded, and obliterated 3.1ghz athlon in multithreaded apps. So even so called disastrous CPU like Phenom was quite a progress for AMD.
So according to 501 numbers BD is even worse than k10 launch
