The Mobility Radeon 7500 is similar to (or even the same chip as) the desktop Radeon 7500 with lower memory clock and slightly lower core clock.
The Geforce2 Go is based on a Geforce2 MX with a lower clock and the same memory clock.
So the Radeon should be a lot faster that the Geforce.
Confirmed in this article (which incidentally benchmarked an Inspiron 8100 once with a Geforce2 Go 32 MB and once with a Radeon 7500 64MB).
Even 16 MB vram should be ok. When I played Pod Racer I had a Rendition card with 8 MB and the game ran fine.
