Minimum 10,000 PassMark points
8 GB+ graphics card memory.
DirectX 11 compatible.
The CPU should have as high a GHz value as possible, ideally 4.2+ GHz.
Examples: NVIDIA RTX 2080 Ti (11 GB memory), NVIDIA Titan RTX (24 GB memory)

Minimum 6,000 PassMark points
4 GB graphics card memory.
Rendering movies in 4K resolution (3840x2160 pixels) requires a minimum of 6GB graphics card memory.
