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 Z840 is recommended if you require dual processors or dual high performance graphics cards. The Z840 can support up to 6 hard drives or 10 SSDs.

The Z640 is recommended if you require a single high-end processor or single high-performance graphics card. You can always add a second processor and double the memory at a later date using the optional Z640 processor riser. The Z640 can support up to 4 hard drives or 6 SSDs.

The Z440 is recommended if you require a single processor with a low core count or mid-range graphics card. The Z440 can support up to 4 hard drives or 6 SSDs.
