Well, I wouldn't say that the figures you just posted back up the statements that the Efika's "Speicher ist so verdammt schnell" and that the Efika's "RAM-Speed haut da gewaltig rein".
And as for "den G3 600 steckt es locker weg" I'm not so sure as well:

As you can see, your Efika is faster at writing but slower at reading. And that's compared to a machine with a crippled northbridge (assuming the Peg2 G3 has better memory performance than Peg1 G3).
