I agree SB ST performance most likely will be higher at the same clock than BD's, but BD strength should be MT. AMD focus for BD is on MT and scalability.

I see it like this:
if BD really can hit 4.8-5.x GHz on AIR stable for all 8 cores under load then it's great and will have amazing performance in MT. Scaling 8 cores to that speed is harder than 4. Just look at Intels SB vs Gulf. 6 core monster scales up to 4.4-4.6GHz on AIR.
When ST performance is your goal I bet you can squeeze extra few hundred MHz out of BD max MT clock.
Youre comparing it as if 8 BD cores were fully comparable to 4 intel cores with HT.They are not, its different approach.
Gulftown is based on older tech than SB, and less (probably much less) mature process, so again i dont see it as viable comparison.
AMD positions 8 core BD`s to 4 core SB`s , so thats where comparisons have to be made.Its more like 4 modules vs 4 cores.Or 8 cores vs 8 threads.
One AMD core is much smaller than one SB core.So its pretty much destined to have lower ipc.Thus it would be expected of them to reach higher clocks.
And its been known for some time that BD is architectured as high speed cpu.So its not unreasonable to expect it reach higher clocks.
I hope for fully customizable turbo.If i can set 8 cores to 5ghz, then maybe 5.5ghz in single/dual threaded work.That should help.But its yet to be known how turbo v2.0 works.
