Data confidence
This comparison uses 6 measurements. 6 are community-reported.
All numbers reflect generation speed (tok/s) at the best available quantization for each side. Quantization levels may differ between families. Where quant levels differ, the comparison shows each chip at its measured best — not a controlled variable.
