Local AI performance
What the SPARKLE Arc Pro B70 Blower can run on your own machine, and how fast. Capacity and speed come from the Intel Arc Pro B70 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.
