AMD Ryzen Embedded R1600
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.
Four-bay Synology with a Ryzen Embedded R1600 and no iGPU, so Plex cannot use Quick Sync. NASCompares forced single-file transcodes on the stock RAM configuration.
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.

NASCompares — DS423+ vs DS923+ Plex tests (DS923+)Paired with the DS423+ row from the 26 Feb 2024 NASCompares comparison. No watt figure and no simultaneous count in that section.
NASCompares could not get a single forced Plex transcode of 4K HEVC to play on a stock DS923+ (10-bit 16 Mbps, 8-bit 60 Mbps, and 8-bit 29 Mbps all failed). Several 4K H.264 files in the 12–40 Mbps range were a clear pass, one file at a time. There is no iGPU, so this is software.

NASCompares — Synology DS923+ 4K Plex tests4 Feb 2023. Ryzen Embedded R1600, tests over 1 GbE with the player forced to transcode. Clear pass includes IMAX 4K H.264 40 Mbps, another 4K H.264 40 Mbps, 4K H.264 12 Mbps, 4K H.264 32 Mbps, and a 100 Mbps 1080p H.264 file. Fail: UHD 4K 10-bit 16 Mbps HEVC, 4K HEVC 60 Mbps, and two 4K HEVC files around 29 Mbps. Tone mapping is not available in hardware on this CPU.
