Cinema 4D System

The physical render engine built into C4D is a CPU-based render engine that benefits greatly from a hi-core count processor. 24GB of RAM recommended but performance scales with additional RAM so more is better. 128GB is ideal. CPU intensive so GPU doesn't matter unless utilizing VRAY, REDSHIFT or OCTANE RENDER plugins. In those scenarios they scale with multiple GPU and work best with GPUs that have 24GB or more VRAM.
