Intel or AMD?
AMD. Athlon 64 3000+ to be precise.

I gather these use algorithmic optimisations.
Both. Versions 1-4 are progressively algorithmic, version 5 includes low-level
optimizations (mostly manual inlining and unrolling). Implementing version 1
is probably also interesting: it is the most concise version.
BTW, the ray tracer leverages the semantics of the float infinity (as the
parameter when there is no intersection). Shouldn't be a problem but some
compiler options might break it.
Thus far the Haskell version generates identical images to the OCaml
one.
