Can the AMD Radeon RX 7900 XTX run ChatGLM3-6B?

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

ChatGLM3-6B on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 65k 50.4-61.6 t/s ~2.1-2.6 (slow)
Q8 yes 111k 100.8-123.2 t/s ~4.2-5.1 (slow)
Q4 yes 131k 180-220 t/s ~7.5-9.2 (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.

Can the AMD Radeon RX 7900 XTX run ChatGLM3-6B?โ–ถ

Yes. At Q4 it generates ~180-220 tok/s and fits up to 131k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~7.5-9.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 131k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
