Let's see:
2600K on average gets 213.4pts. 1100T gets 165.8pts. 10% slower than 2600K for 3.6Ghz Zambezi would mean 213.4/1.1=194pts. This in turn is around 16% faster than 3.3Ghz X6 Thuban according to the chart. Note that Zambezi has 9% clock advantage.
So basically you expect that Bulldozer design,which is a:
-whole new uarchitecture,with many bottlenecks from K8/K10 removed and better utilization of execution units,new redesigned int and fp pipelines,
-33% more cores,
-13% higher Turbo core clock : 4.2Ghz vs 3.7Ghz (which now runs across 4 cores and not only 3),
-higher default clock of 9% (3.6Ghz vs 3.3Ghz),
-somewhat higher IPC in integer/fp(as per AMD)
-better power management
to run slower than Thuban 1100T. Do you see the problem in your logic? Zambezi will not be only 16% faster than Thuban. Turbo core ALONE will get you there,disregarding the effect of 33% more cores or improvements in the cores.
