Seriously, I have no idea why people are still crying about Bulldozer. Sure it's not the fastest chip,but at least it is overall faster than Thuban(sometimes a lot ,sometimes it's even slower). The good thing is that even in this worst case scenario when both design and process have some issues,it's quite a decent product. It just needs a price correction to be a bit more competitive from price/perf. POV.
Piledriver will improve on Bulldozer,Steamroller on Piledriver etc. The curve goes to the right direction so I don't know why some people are so pessimistic... If anyone thinks that AMD could have rode K10 on sub 32nm with 4+GHz clocks and 8+ cores with no changes to the uarchitecture itself is delusional.
