This was modeled with Maya, rendered with Redshift, with all Redshift materials.  Redshift is a GPU renderer and the render time was somewhat shorter than my experience with Arnold, but perhaps only roughly 1/2 as long.  However, I was using a consumer grade graphics card (Nvidia 1080 founders edition).
