Stable LM 2 12B on the AMD Radeon Pro W7900 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 112k 22.4-27.4 t/s ~1-1.3 (slow)
Q8 yes 186k 44.8-54.8 t/s ~2.1-2.5 (slow)
Q4 yes 219k 80-97.8 t/s ~3.7-4.5 (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.
