Arnold

Processor

Rendering

Arnold is a CPU-based, multi-threaded rendering application, therefore the more processor cores the better.

Memory

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

Storage

We recommend having two drives which provides the best performance:

1. Primary Drive: SSD for the operating system and software
2. Secondary Drive: another SSD, or for better performance, an NVMe Flash Storage Drive (the "HP Z Turbo 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.

Chassis

The HP Z8 G4 Workstation is recommended if you would like dual processors and/or multiple high performance graphics cards.

The HP Z6 G4 Workstation is recommended if you would like to start with a single 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.

The HP Z4 G4 Workstation is recommended for 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 HP Z4 G4 has an optional 1000W power supply that will support the most powerful graphics cards inluding the GeForce RTX 2080Ti and Quadro RTX 6000.
