If this came out two years ago then it would have been on 45nm.
I don't see how making it hotter and slower would have made it any more competitive "in its day".
How did that work out for Phenom? What Phenom needed, and eventually got, was a shrink from 65nm to 45nm. It did not need to be released 2yrs earlier on 90nm.
Now if what you meant to say is that the BD we are going to see released this summer (i.e. the 32nm one) should have come out two years ago then yes, I totally agree. A 32nm-based BD in 2009 would have rocked.
Well moving to a smaller die size is the same with the entire product execution. Intel has been on 32nm for what 2 years or so now? I believe the original Bulldozer has always been designed for 32nm, I might be wrong on that.
