I was wondering what would be the major differences between ATi 9200 and 9700 graphics processors. From what I can see when checking out two Sony Vaio laptops, the only difference is the memory. Obviously there are other differences but not sure what they are.
i dunno about the 32mb mobility radeon 9200, but the 32mb mobility radeon 9000 was only 64-bit compared to the 64mb version being 128-bit. This made it significantly worse in all 3d-based programs (4500 in 3dmark2001 compared to 7000 for the 64mb). Ive got a 9200 64mb in my laptop, and it can run most games pretty well, doom3 is a bit laggy but farcry runs well.
If you can u should go for the 9700. it would have roughly the performance of a desktop 9600 pro.
Basically, you will find that the 9700 64mb is roughly 2x as fast as the 9200 32mb.
