    I dunno man.Take a look at the previous 65nm and released 45nm Shanghai parts. The Core clock : NB clock ratio never went above 1.3.
    For example: Phenom 9350 model has a ratio of 2.3/1.8=1.27; Phenom 9850 2.5/2=1.25; Phenom 9950 2.6/2=1.27;Shanghai 2384/8384 model has a ratio of 2.7/2.2=1.22

    Now compare those ratios to unreleased Phenom II chips ratios: Phenom II 920 2.8/1.8=1.55 (way too high ratio);Phenom II 940 3/1.8=1.66 (way way to high ratio) double .

    It is entirely possible desktop parts will receive these NB clocks,but in the light of Shanghai parts,i'm very skeptical...

    What would be "normal" NB clocks if we follow the trend seen in Phenom I and Shanghai? It would go like this:

    Phenom II 920 model : 2.8/1.22=2.3Ghz in best case or 2.8/1.27=2.2Ghz in "worst" case.The 2.2Ghz would be my bet following the rule of integer NB multies,Shanghai NB clocks and 1.27x ratio seen from Phenom 9950.So 2.2Ghz for 920 model.

    Phenom II 940 model : 3.0/1.22=2.45Ghz in best case or 3.0/1.27=2.36.This time i would say the NB would probably be between these two frequencies, following the rule of 200Mhz increments and integer multies. So 2.4Ghz for 940 model.

    Like i said previously,maybe the retail parts will indeed have 1.8Ghz NB clock so the above "math" is pointless.But even so,it makes sense to me.
