Nothing stays in AMD's path this time .. they have the very advanced 32nm process .. the CPU is not cache starved like the 1st Phenom was ... is not held back by 3rd party chipsets ... Physically and engineering-ly the CPU is very much OK ... The only thing they lack is the right software.
I've red 5 different review last night and one thing became so obvious .. with the right settings, Bulldozer can surpass even 2600K in 50% of the applications used in all the reviews ... The architecture is clearly NOT inferior to SB ... may be better even but not everything can be done in hardware. This is only thing that AMD seems not to be getting .. especially since this issue has been so obvious in the last 10 years .
