What the Radeon PRO W7800 48GB can run on your own machine, and how fast.
Largest model it can run (8K context)
- Q4 (the usual choice, near-original quality)
- ~68B
- Q8 (closer to original, half the model size)
- ~40B
- FP16 (unquantised, for training and research)
- ~21B
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 |
|---|---|---|---|
| Qwen2 Math 72B | 72.7B | 43.9GB | 13-16 tok/s |
| Dolphin Llama3 70B | 71.0B | 42.7GB | 14-16 tok/s |
| Llama3 Chatqa 70B | 71.0B | 42.7GB | 14-16 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.
