Magistral Small 1.2 on the NVIDIA H100 SXM5 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 92k 50.9-60.7 t/s ~0.6-0.7 (slow)
Q8 yes 183k 101.9-121.4 t/s ~1.2-1.5 (slow)
Q4 yes 224k 182-216.9 t/s ~2.2-2.6 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.
