AMD Ryzen 9 7950X3D (test host) · NVIDIA GeForce RTX 4090

In Jellyfin, one 67.4 Mbps 4K HDR10 remux tone-mapped to 4K at about 200 fps on an RTX 4090, and to 1080p with subtitle burn-in at about 240 fps. 1080p-to-1080p clips landed around 800–900 fps. This is a single session, not a pile of clients.

A high-end desktop GPU. The Jellyfin numbers below are single-stream speeds on a 7950X3D host, measured so the CPU and 3D engine would not be the bottleneck.

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

Host: Ryzen 9 7950X3D, 64 GB DDR5, RTX 4090. A 41.5 Mbps 4K HDR Blu-ray was about 250 fps at 4K with burn-in and about 400 fps to 1080p. The author says one NVENC engine should sit at full load because the CPU and 3D engine were not the limit, and split-frame encode would not show up on a single H.264 session.

The card could pull over 150 W while transcoding and hit its maximum frequency. One NVENC engine on a single session.
