CPU rendering focuses on accuracy while GPU rendering is optimised for speed. From version 6 Autodesk Arnold is able to use both CPU and GPU rendering. We recommend focusing on the CPU up to version 5, as the graphics card cannot be used for its renderings. Intel Xeon processors typically have more threads than their Intel Core counterparts. Multiple queues per core allow the CPU core to switch between different tasks. CPU cores refer to the cores that actually physically exist, while threads are often thought of as queues for the core in question. The CPU renderer uses all available threads of the CPU. For these versions we recommend to pay attention to a balance between the number of their CPU cores and threads. Up to version 5, Arnold is a CPU-based rendering program. Plug-ins are available for the following programmes: Maya, 3ds Max, Houdini, Cinema 4D, Katana and Softimage.

From version 6 Arnold is able to use the CPU and GPU for its renderings. Autodesk Arnold is part of Autodesk Maya and Autodesk 3ds Max as an interactive renderer. Over 300 leading studios and production houses use Arnold as their standard renderer. Arnold is a ray-tracing renderer program from Autodesk for calculating three- dimensional, computer-generated scenes and has become one of the most widely used rendering programs in professional film production worldwide in recent years.
