With such small L2s , how can they feed a highly complex core with 2 threads ?? Multiple threads means cache thrashing , small size amplifies that and you have a slow L3 behind it.
If that's a good cache subsystem , I'm stupefied.It goes against everything Intel has done lately ( large , shared , extremely fast L2s which thrashed IMC equipped CPUs ).
What about the FSB ? DP Nehalem uses QPI , that works at speed of up to 4.8GTs.How does CPU-Z read that ?
