Median of 1 submissions (0 outliers excluded), interquartile range 1247.99–1247.99; submissions 2021-05-16 to 2021-05-16; CUDA backend. Snapshot 2026-11-14.
- B · NVIDIA GeForce RTX 3060 12GB
- 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.
