4 Things to Know About 64GB RAM for Blender Cycles

More RAM won’t speed up renders if your scene fits in 32GB Rendering is compute-bound, not memory-bound. Once you have enough RAM to avoid swapping, adding more does not make the CPU or GPU go faster.

64GB only helps when your scene exceeds 32GB If your scene pushes past 32GB, the OS starts paging to disk, which destroys render times. In that case, 64GB prevents that slowdown.

For most users, 32GB is plenty Even heavy Blender users rarely need more than 32GB for CPU and GPU rendering with Cycles. The real bottleneck is usually the GPU itself.

Spend extra money on a faster GPU instead Unless you routinely work with multi-million polygon scenes, 8K textures, and hundreds of instances, a better GPU will actually cut render times. 64GB is overkill for most workflows.
