Can the AMD Radeon RX 6800 XT 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 6800 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 9k 26.9-32.9 t/s ~2.1-2.6 (slow)
Q8 yes 55k 53.8-65.7 t/s ~4.2-5.1 (slow)
Q4 yes 75k 96-117.3 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.

FAQ

Can the AMD Radeon RX 6800 XT run ChatGLM3-6B?โ–ถ

Yes. At Q4 it generates ~96-117.3 tok/s and fits up to 75k 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 75k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
