Local AI performance
What the PNY RTX PRO 4000 Blackwell SFF can run on your own machine, and how fast. Capacity and speed come from the RTX PRO 4000 Blackwell SFF 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)
- ~32B
- Q8 (closer to original, half the model size)
- ~19B
- FP16 (unquantised, for training and research)
- ~10B
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
- Speed, 8B model at Q4
- 66-76 tok/s
- Memory bandwidth
- 432 GB/s
- Price per GB of VRAM
- €133.29
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 |
|---|---|---|---|
| Llava 34B | 34.8B | 21.5GB | 16-19 tok/s |
| Yi 34B | 34.4B | 21.5GB | 16-19 tok/s |
| Nous Hermes2 34B | 34.0B | 21.6GB | 16-19 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.
