Render VRAM / RAM Requirement Estimator
Estimate the GPU VRAM a render needs from texture, geometry and frame-buffer memory — so a scene doesn't fall back to slow out-of-core rendering.
GPU renderers (Redshift, Octane, Cycles GPU) are fast until the scene exceeds VRAM, then they crawl with out-of-core paging or fail. A 4K render with many AOVs and big textures can blow past a 12 GB card. Estimate before you start so you pick the right card — or optimize textures down to fit.

Frequently asked questions
What does Render VRAM / RAM Requirement Estimator do?+
Estimate the GPU VRAM a render needs from texture, geometry and frame-buffer memory — so a scene doesn't fall back to slow out-of-core rendering. GPU renderers (Redshift, Octane, Cycles GPU) are fast until the scene exceeds VRAM, then they crawl with out-of-core paging or fail.
Is my data private?+
Yes. Render VRAM / RAM Requirement Estimator runs entirely in your browser — your inputs are never uploaded, stored or logged.
What standard or source is Render VRAM / RAM Requirement Estimator based on?+
It follows GPU renderer memory documentation (Redshift/Octane/Cycles). Always confirm against the current official document, as specifications and rates can change.
What formula does it use?+
Render VRAM / RAM Requirement Estimator uses: VRAM ≈ textures + geometry/BVH + (W×H×4 channels×4 bytes×AOVs) + ~1.5 GB engine overhead. The tool shows this formula with your own numbers substituted so you can verify the result.
