3 to 4 % of Barcelona can go over 2.6 GHz
 

We learned that three to four percent of K10 Barcelona processors can actually hit speeds higher than 2.5 or 2.6 GHz. This is finally good news as AMD doesn’t need much more of these super fast CPUs to beat Intel in the high end. The trouble is that the majority of CPUs are doomed to life under 2.5 GHz. These chips are reported to hit between 2.8 and some of them even 3.0 GHz which is exactly how much AMD needs to compete with Penryn and the current Intel 65 nm Quad cores.

now all we need is to see how those 2.5 Ghz parts go vs the 3.33 Penryn
