Recommended Workstation Specification for ARNOLD Application
May 15, 2019


Rendering is a highly multi-threaded task and therefore a high amount of CPU cores will provide better performance. Arnold is a CPU-based, multi-threaded rendering application, therefore the more processor cores the bette

Memory:   3-6GB of RAM per CPU core is basically required. For example, if you select a single 12-core processor, 32GB will suffice for basic tasks or 64GB for more demanding workloads.


Primary Drive: 480SSD for the operating system and software

Secondary Drive: Another SSD, or an NVMe Flash Storage Drive for active project files. If you need additional storage for large, infrequently accessed files, we also recommend one or more 4TB, 6TB or 8TB+ hard drives. Hard drives also work well for storing export files as the export/rendering process is generally not write intensive.

Graphics: Arnold has no graphic card or GPU requirements because it is purely a CPU-based renderer. Therefore a lower-end graphics card is recommended, such as the NVIDIA GeForce GTX 1070.


Select HP Z8 G4 Workstation/ Dell T7920 Precision Workstation if you would like dual processors and/or multiple high performance graphics cards.

Select HP Z6 G4 Workstation/ Dell T7820 Precision Workstation to start with a high-end processor and single high-performance graphics card with the potential of upgrading in the future. With the Z6 G4, you can add a second matching processor and double the memory using the optional second processor riser. The power supply will also support two mid-range graphics cards.

Select HP Z4 G4 Workstation/ Dell T5820 Precision workstation majority of workflows. Since Intel now produces single Core i9 and Xeon processors with up to 18-cores and high clock speed, there is no need for dual processors unless you will have heavy CPU rendering or intensive tasks demanding more than 18-cores. Also, the Single Processor Workstation has an optional 1000W power supply that will support the most powerful graphics cards including the GeForce RTX 2080Ti and Quadro RTX 6000.


Arnold is an advanced Monte Carlo ray tracing renderer built for the demands of feature-length animation and visual effects. Originally co-developed with Sony Pictures Imageworks and now become their main renderer.
