x stands for one core performance of K10
y stands for one integer core performance of bulldozer

The result is : 1.25x=y. So bulldozer will stronger than K10 about 25% in single core performance.

If I was wrong please correct me.
I was just calculating on the numbers JF-AMD gave me. And stating that I hope for much greater performance increases.

What you are saying is that Bulldozer will loose relative performance in multithreaded applications. That's the opposite of what AMDs claims.

If AMD talks about multithreaded performance all the time, it's reasonable to believe that it's in this field that BD will be making the greatest improvements: And if JF-AMD is correct when he says 50% higher total throughput with 33% more cores, that means 12.5% higher performance than MC per core in the area that Bulldozer was supposed to shine.
My question is, if that is the case, how is the performance in the scenarios AMD don't talk about?
