What CPU does the Synology DS1623xs+ use, and how does it compare to the DS1621+?

Regarding the Synology: The DS1623xs+ runs an AMD Ryzen V1780B quad-core clocked at 3.35 GHz — a faster spin of the same AMD platform found in the DS1621+. Same caveat applies: no integrated GPU for transcoding, but those Ryzen cores are excellent for raw storage throughput and file serving.
