Are these implementations close enough to even compare meaningfully?

[It seems like about 95% of the cpu time in raytracing goes to searching
for ray-surface intersections -- acceleration structure searching plus
primitive intersection tests -- so I suppose one could easily make a
fairly small test case that tested only those things, and make sure to
use the same algorithms for both languages, etc.]
