Yes โ€” here's how fast and up to what context, with real measured numbers.

CausalLM 14B on the AMD Radeon Pro W7900 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 81k 18.5-22.6 t/s ~0.9-1 (slow)
Q8 yes 171k 37-45.3 t/s ~1.7-2.1 (slow)
Q4 yes 210k 66.1-80.8 t/s ~3.1-3.7 (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.

FAQ

Can the AMD Radeon Pro W7900 48GB run CausalLM 14B?โ–ถ

Yes. At Q4 it generates ~66.1-80.8 tok/s and fits up to 210k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.1-3.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 210k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
