Local AI performance
What the GIGABYTE Radeon PRO W7800 AI TOP can run on your own machine, and how fast. Capacity and speed come from the Radeon PRO W7800 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)
- ~44B
- Q8 (closer to original, half the model size)
- ~26B
- FP16 (unquantised, for training and research)
- ~14B
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
- 87-102 tok/s
- Memory bandwidth
- 576 GB/s
- Price per GB of VRAM
- $65.62
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 |
|---|---|---|---|
