Can the AMD Radeon RX 7900 XTX run OpenThaiGPT v1.0.0 (7B)?

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

OpenThaiGPT v1.0.0 (7B) on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 53k 44.4-54.3 t/s ~1.9-2.3 (slow)
Q8 yes 105k 88.8-108.5 t/s ~3.7-4.5 (slow)
Q4 yes 128k 158.6-193.8 t/s ~6.6-8.1 (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.

Can the AMD Radeon RX 7900 XTX run OpenThaiGPT v1.0.0 (7B)?โ–ถ

Yes. At Q4 it generates ~158.6-193.8 tok/s and fits up to 128k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~6.6-8.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 128k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
