I couldn't tell you. Considering that this is a Mini and not a battery operated device, I imagine so, but the system profiler doesn't mention this and it'd need to be tested.
Thanks for looking into that for me, I'm hoping that those figures are an underclocked 2D mode.
I'm asking these questions as I need a system that is small & cheap to run.
The system would also have to do some gaming though (dawn of war, C&C3 COD4 ect...) having done some research the 9400 is just about fast enough. (at 580/1400mhz that is)
That's why I thought I'd ask as I know Apple has a habit of underclocking their IGP's. 350/800 isn't going to cut it I'm afraid
