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 113 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 | Intel |
|---|---|
| Type | NAS (network attached storage) processor |
| Share of memory for models | 88% (what the NAS system and its storage services typically leave free at this size) |
| Chip | Intel Atom C5125 |
| AI accelerator | None. Models run on the processor cores. |
| NAS models with this chip | QNAP TS-855X · QNAP TS-1655 · QNAP TS-h1655XeU-RP · QNAP TS-855eU-RP · QNAP TS-855eU |
| Memory type | System RAM, shared with the NAS operating system and its storage services |
| Bandwidth figure | 23.5 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. |
