Looking at Cinebench screenshot comparing the 1100T singlethreaded vs multithreaded, the difference is a 5,261261261 speedup, which is explained by the fact in the single threaded load the 1100T is running at 3,7ghz, while in the multithreaded test it's running at 3,3ghz. Those CPU Passmark benchmarks posted above are very well multithreaded so we'll assume it will show roughly the same scaling going from multithreaded to singlethreaded:

6314/5,261261261 = 1200 for the 1100T @ 3,7ghz

Now we know from movie posted about Bulldozer running Fritz Chess benchmark, that turbo in single threaded workloads can keep Bulldozer running at 4,2ghz with 1-2 cores loaded, while it runs at 3,6ghz with 8 cores loaded. Also, the cores are running at 80% efficiency when both cores in a single module are loaded, so instead of dividing by 8, we'll be dividing by:
8*0,8 = 6,4.
We also shouldn't forget the speed difference in multi and single threaded tests:
4,2/3,6 = 1,166666667

This brings Bulldozers calculated single thread score to:

8681/6,4*1,166666667 = 1582 for 8150 @ 4,2ghz

This gives Bulldozer a 1582/1200 = 1,319 or 31,9% speedup compared to thuban in single threaded workloads at stock speeds with turbo enabled for both.

OR

(1582/4,2)/(1200/3,7) = 1,162 or 16,2% IPC boost


Disclaimer: This is all just some theorycrafting, but it feels right about what to expect. Take these calculations with a grain of salt however

If this is true, I was _very_ close with my math skillz =)
