Intel Arc A380
A Plex stress-test post reports 24 simultaneous transcodes of 4K HDR at 35 Mbps down to 1080p at 10 Mbps on an Arc A380, with no hitching or buffering. The title does not say whether tone mapping was enabled. 2 other reports on this page.

Synology DS423+
On Plex 1.31.2, three clients playing the same 4K file sat near 20% CPU until one stream was forced from 4K down to 1080p. That single transcode made two of the three streams buffer. Forcing 1080p down to 720p stayed in the 20–30% CPU range and was called a good result. 2 other reports on this page.

NVIDIA GTX 1650
On Windows, a GTX 1650 (TU106) with a patched NVENC session limit handled more than ten 1080p Plex transcodes, two 4K streams with tone mapping off, and could not hold a single 4K HDR to 1080p stream with tone mapping on. 1 other report on this page.

Synology DS923+
The same 720p-to-480p Plex transcode was easy on the DS923+ even without an iGPU. The review says the harder 720p-to-240p conversion is where it fell behind the DS423+'s Quick Sync. One file at a time. 1 other report on this page.

Intel Core i5-12500
An i5-12500 owner tested five simultaneous 4K Plex transcodes on UHD 770 and said they all worked. They did not try a sixth, and the comment does not state bitrate or tone mapping.

Intel Core i5-12500T
An i5-12500T owner got twelve 4K Plex streams transcoded down to 720p on UHD 770 and said the iGPU still had more left. Tone mapping is not mentioned.

Intel Core i5-12600K
A Plex user said a Core i5-12600K handles about ten 4K transcodes on its iGPU, with no separate graphics card. The comment does not say HDR, tone mapping, bitrate, or operating system.

Intel Core i5-13500H
An i5-13500H (Iris Xe, 80 EUs) handled five 4K remuxes at once in Plex with tone mapping and subtitle burn-in, down to 1080p at 8 Mbps. The commenter called it easy.

Intel Core i9-11980HK
An i9-11980HK owner reported eight 4K HDR remuxes at once in Plex, with tone mapping and subtitles, down to 1080p at 8 Mbps. They think the iGPU has the same media-encoder count as UHD 770, from the generation before it.

Intel NUC 11 (i5-1135G7)
A NUC 11 with an i5-1135G7 (Iris Xe) produced ten tone-mapped 4K Plex transcodes in one owner's testing. Bitrate and operating system are not in the comment.

Minisforum MS-01 + Sparkle Arc A310
Plex on a Minisforum MS-01 with a Sparkle Arc A310, tone mapping set to Hable, held five 4K HEVC streams at once: three at 40 Mbps and two browser streams around 58 Mbps, while the server was still importing the library.

NVIDIA RTX 4060
A Plex user said an RTX 4060 did 15 streams of their 15 highest files. The same comment guesses a future HEVC-encode mode might land nearer six streams, which is a prediction, not a result.
