Median of 1 submissions (0 outliers excluded), interquartile range 118.55–118.55; submissions 2022-02-12 to 2022-02-12; CUDA backend. Snapshot 2026-11-14.
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.
