Does anyone know what the capabilities of the graphics cards on the powerbooks are? I saw that the 12" ones come with geforce fx (mobile) cards, and the larger ones have mobility radeon 9600s. Do either of these cards support fragment shaders, or other fun stuff like that?
Even better, if someone knows what Cg fragment profile one can use, that would help a lot. I’m thinking of getting a powerbook to replace my current laptop, and I’d love to find something that supports decent graphics stuff 
Both support ARB_fragment_program. You can usually find details here: http://developer.apple.com/opengl/extensions.html , but it hasn’t been updated in a while…
AFAIK, Cg doesn’t officially work on Mac OS X. I have had some success building the NVidia Linux SDK on the Mac though, so YMMV.
Thanks! I had found the extension list, but since no geforce FX cards were listed, I figured it might be a bit out of date… So as I understand it, basically the mobile fx card is a full-fledged fx (not like the gf4 compared to the gf4mx), and the mobile ati is a full radeon, just both are probably a bit slower due to power and heat constraints. Thanks for the info.
Here are the stat’s on my powerbook’s 9600.
