Professional OpenGL Performance - SPECviewperf 6.1.1
Advanced Visualizer is clearly limited by GeForce's fill rate. Only Irongate with its missing AGP4X support is not quite reaching the ceiling.
The story is different with the CAD-program 'Design Review'. Here Giga-Athlon is pretty much on par with Giga-Coppermine on i840 or BX. SPECviewperf is the one benchmark set where BX doesn't look quite as good anymore and where i840 is really able to kick ass. You can see once more that VIA's Apollo Pro 133A is not good for professional workstation software. It scores by far worst.
