In reply to my corresponding request on the ffmpeg-user mailiing list:
https://ffmpeg.org/pipermail/ffmpeg-user/2024-December/058931.html

    /My tests even with the NVIDIA drivers are pretty much the same as
    Intel's./
    /Perhaps AMD's RADV performs better in this front?/
    /Will retest as soon as I get my hands on one of these AMD GPUs.
