Blender Open Data (Blender Foundation)
Median of 1 submissions (0 outliers excluded), interquartile range 1298.45–1298.45; submissions 2022-01-07 to 2022-01-07; CUDA backend. Snapshot 2026-11-14.
- B · NVIDIA GeForce RTX 4060 Ti 16 GB
- no comparable result
difference = |A − B| ÷ the smaller value × 100%. The 5% noticeable threshold is a UX heuristic, not statistical significance.
Render time of a single Cycles scene without synchronization. Median of submissions after filtering.
