Apple M4 · 10-core Apple GPU

On a 16 GB M4 Mac mini, Jellyfin tone-mapped a 67.4 Mbps 4K HDR10 remux to 4K with subtitle burn-in at 61 fps (H.264, VideoToolbox) and 102 fps (HEVC). The same file to 1080p with burn-in was about 140 fps. A 41.5 Mbps 4K HDR Blu-ray to 4K HEVC was about 130 fps.

16 GB M4 Mac mini in the same Jellyfin clip suite as the N100 and M1 Pro. The author preferred HEVC output and noted weak image quality at low bitrates.

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

CPU-only H.264 on that clip was 58 fps, so the media engine was only a small step up for AVC. The author says the M4 was up to twice the N100's framerate at less than half the power, without giving a watt figure, and that 8 Mbps output looked poor (the media engine will emit 1440p at that preset). 1080p did not scale linearly with the 4K speedup.
