Segment Anything Model on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 295k 475.5-581.1 t/s ~19.8-24.2 (slow)
Q8 yes 304k 950.9-1162.3 t/s ~39.6-48.4 (slow)
Q4 yes 309k 1698.1-2075.5 t/s ~70.8-86.5 (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.
