    Blender Open Data (Blender Foundation)

    Median of 30 submissions (0 outliers excluded), interquartile range 161.85–248.57; submissions 2025-07-17 to 2026-03-08; CPU backend. Snapshot 2026-11-15.

    difference = |A − B| ÷ the smaller value × 100%. The 5% noticeable threshold is a UX heuristic, not statistical significance.

    Cycles render in Blender Benchmark. Median of the sum of samples per minute over three scenes after removing outliers.
