Running AI on the QNAP TVS-h877AX

Yes, it runs AI models on the NAS itself. Models run on its CPU cores, and this configuration leaves about 173 GB for them after the NAS system and its storage services. The grades below assume the NAS isn’t busy with backups or media work at the same time. More memory is the upgrade that matters most: see the configurations.

Spec sources

Estimates come from published hardware specs and our open formulas, not from running the model on your machine. Real speed varies with runtime, drivers and settings. Numbers marked “Measured” come from a linked benchmark.
