QuantFits?Max contextSpeedBeyond context
FP16 yes 249k 35.7-43.7 t/s ~0.3-0.3 (slow)
Q8 yes 392k 71.5-87.4 t/s ~0.5-0.7 (slow)
Q4 yes 455k 127.7-156 t/s ~1-1.2 (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 Instinct MI300X 192GB run GRITLM 8x7B?โ–ถ

Yes. At Q4 it generates ~127.7-156 tok/s and fits up to 455k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1-1.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 455k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
