Intel Q9450 vs Phenom 9850 - ATI HD3870 X2

And can you prove that it's the FSB that limits them on that test ?

Give me an Intel Rig and i sure will . And again the FSB does not limit bandwidth wise, it all depends on the prefetcher and how well its actually working.

Anandtech:
This is the test that actually screws the whole thing for Intel. It turns out that CBALLS2 calls a function in the Microsoft C Runtime Library (msvcrt.dll) that, when combined with Vista SP1, can magnify the Core architecture's performance penalty when accessing data that is not aligned with cache line boundaries.

"Wrong" Data in the Cache (simplyfied) -> accessing memory -> high latency -> bad coherency -> bad performance
