I’m going to get a new laptop (my first Apple) next week and one of the main uses for it will be OpenGL developement on the go. I need a really small laptop, so I won’t be going over 12" and thus my choices are basically limited to the lowest-end G4 iBook and 12" PowerBook. PowerBook would otherwise be the safe bet, but how does its GF FX 5200 Go compare to iBook’s Mobility Radeon 9200 performance- and feature-wise?
All the (massively game-oriented) comparisons I’ve been able to find have suggested that Radeon would be a better performer, but as I’m not all that much into games, I would be willing to sacrifice some speed for more supported extensions / overall better OpenGL support.
So do any of you have any experiences on either or even better, both?
I recently have had the opportunity to compare the 14" iBook and the 12" Powerbook, along with a bunch of desktop GPUs. My tests are particular to my in-development apps (not games) though so take this as one person’s (biased) opinion.
Fill rate test: (drawing overlapped blended 800x600 textures at 60fps, how many can be stacked before dropping frames?)
Radeon 9200: 7
GFgoFX5200; 9
for comparison:
Radeon 9600 mobility (in Powerbook g4): 21
GFFX5200 (in G5): at least 32.
