I can recall it being used as a useful benchmarking tool once it got
multicore.

If you use so many triangles so that each are smaller than a screen
pixel, you lose no more accuracy than any pov primitive.
In any cases, you get it wrong: the amazing speed up is not due to
native GPU triangle handling, but faster ray intersection calculations
thanks to the GPU sheer parallel vector processing. You can see that in
smallptGPU where you get perfect math spheres much faster, no meshes in
sight.
