B2 is supposed to enable higher clocks. Maybe something needed to be sacrificed to get there?

I am not sure at what stepping Barcelona is now, but I just did some testing with the B2 stepping at 2.5 GHz, and it seems that contrary to what some people have been claiming, that this stepping has actually a slightly slower northbridge.

Raw Bandwidth numbers are up to 10% lower than the 2 GHz with an identical configuration (mobo, RAM). Further investigation necessary of course, but the scaling in specjbb (rather mediocre, on both 1.5.0.8 and 1.6 JVMs of sun) seems to confirm this.

Can anyone else with B2 confirm/deny?
