A technician is building a new desktop machine for a user who will be using the workstation to render 3-D promotional movies. Which of the following is the most important component?

3-D promotional movie rendering is an extremely GPU-intensive task. Dedicated GPUs, especially high-end ones, contain thousands of processing cores optimized for parallel computations, significantly accelerating rendering times compared to other components.

DDR5 SODIMM is a type of RAM optimized for small form factors and latest generation. While sufficient RAM is important, SODIMM is typically for laptops, and overall RAM capacity and speed (DDR5) are secondary to a dedicated GPU for rendering performance.

An NVMe disk provides fast storage access, which is beneficial for loading large project files and textures quickly. However, it does not directly accelerate the computational process of rendering frames as much as a powerful GPU.

A 64-bit CPU is a standard requirement for modern operating systems and applications, including rendering software, but for 3D rendering, the GPU typically performs the heavy lifting, making it more critical than the CPU architecture itself (assuming a modern multi-core CPU is already present).
