A NAS with this chip runs models on its processor cores, so memory speed sets the pace: small models (about 1-4B) answer at a usable speed, bigger ones are slow. We plan around 2.0 GB for models, what is left after the NAS system and its storage services. Models run in a container (Docker) or the maker’s app store, and speeds assume the NAS isn’t busy with storage work.
More about this hardware
| Maker | AMD |
|---|---|
| Type | NAS (network attached storage) processor |
| Share of memory for models | 50% (what the NAS system and its storage services typically leave free at this size) |
| Chip | AMD G-Series GX-420MC |
| AI accelerator | None. Models run on the processor cores. |
| NAS models with this chip | QNAP TS-963X · QNAP TS-463XU · QNAP TS-463XU-RP · QNAP TS-863XU · QNAP TS-863XU-RP · QNAP TS-1263XU · QNAP TS-1263XU-RP |
| Memory type | System RAM, shared with the NAS operating system and its storage services |
| Bandwidth figure | 12.8 GB/s, estimated, see the note below |
| Note | One profile for every NAS built on this chip. Memory speed is an estimate from the chip’s supported memory in a typical NAS fitting; a unit with one memory module runs slower than one with two. Speed assumes the NAS is not busy with storage work. |

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.
