Can the AMD Radeon RX 7900 XT run LDM-1.45B?

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

LDM-1.45B on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 214k 173.8-212.4 t/s ~8.7-10.6 (slow)
Q8 yes 236k 347.6-424.8 t/s ~17.4-21.2 (slow)
Q4 yes 245k 620.7-758.6 t/s ~31-37.9 (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 RX 7900 XT run LDM-1.45B?โ–ถ

Yes. At Q4 it generates ~620.7-758.6 tok/s and fits up to 245k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~31-37.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 245k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
