3D Concept has posted some NVIDIA GeForce2 Go benchmarks (in German ~ Babel Fish here). They bench with Quake III: Arena and Motocross Madness 2. More information about NVIDIA’s mobile graphics solution can be found here.
Mea culpa: A closer reading of this article shows that they do not test an actual GeForce2 Go. They use a GeForce 2 MX 32MB 128-bit SDR@143MHz core/166MHz memory (not 64-bit SDR/DDR) to ‘simulate’ GeForce2 Go performance per the specs. Sorry if I misled anybody.
