Hey, just got a 15 inch macbook pro (2.66GHz, 4g ram), and using the framerate on Quake Live as a comparative test the 9400M is outperforming the 9600M GT. On the 9400M the framerate sits at about mid 70s when nothing is happening and drops to about mid 50s at the lowest when action is intensive. On the 9600M GT the framerate sits at mid 40s and drops into mid 30s when a lot is going on. Settings were the same in both cases, set at the highest possible. Intuitively it should be the other way around but I checked the system profiler and the right card was running, so... does anyone have any clue why the hell this is the case? Cheers.
