Apple M1 Pro · 14-core Apple GPU, one media encoder

Jellyfin on an M1 Pro (32 GB, one media encoder) tone-mapped a 67.4 Mbps 4K HDR10 remux to 4K with subtitle burn-in at 48 fps to H.264 and 70 fps to HEVC. A 41.5 Mbps 4K HDR Blu-ray was about 70 fps (H.264) and about 90 fps (HEVC).

Measured on a 2021 MacBook Pro (32 GB) running Jellyfin, as a stand-in for an M1-class Mac mini. Speeds are single-stream.

Reported results

A dash means the source did not count that kind of stream. Single-stream speeds are fps for one file, not a guess at how many clients fit.

Notes from the source

Author's read of the M1 family versus the N100: a bit faster, similar low power, HEVC encode is the faster path. They did not publish a watt number for the M1 Pro. Image-quality complaints in the same post are aimed mainly at the M4 section.
