    Median of 2 submissions (0 outliers excluded), interquartile range 579.94–980.51; submissions 2020-09-15 to 2020-10-14; CUDA backend. Snapshot 2026-11-14.

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

    no data for A

    TGP (NVIDIA) and TBP (AMD/Intel) are calculated differently; higher is not better. For laptops, the chip maker sets the range and the laptop maker picks the value, so the same chip behaves differently in different laptops.

  • Interface

“More” does not always mean “better”: higher power draw or size is a system requirement, not an advantage (such bars are dimmed).
