Local AI performance
What the Nvidia RTX A400 can run on your own machine, and how fast. Capacity and speed come from the RTX A400 chip, so they are the same on every board version; price per GB is this board’s own.
Largest model it can run (8K context)
- Q4 (the usual choice, near-original quality)
- ~3.1B
- Q8 (closer to original, half the model size)
- ~1.8B
- FP16 (unquantised, for training and research)
- ~0.9B
Parameter counts the card holds with room for an 8K conversation, counting the model weights plus its attention cache. A longer conversation needs more memory, so it lowers these figures.
Speed & value

Generation speed tracks memory bandwidth, because every word produced reads the whole model from memory. Shown as a range.
Models that fit, at Q4
| Model | Size | Memory needed | Est. speed |
|---|---|---|---|
| Falcon3 3B | 3.2B | 2.7GB | 35-41 tok/s |
| Llama3.2 3B | 3.2B | 3.0GB | 35-41 tok/s |
| Qwen2.5 3B | 3.1B | 2.2GB | 37-43 tok/s |
Popular models small enough for this card at Q4, one per family. Speed is left blank for mixture-of-experts models, where a bandwidth estimate is not reliable enough to publish.
