Can the Instinct MI455X run GLM-130B?
Yes — here's how fast and up to what context, with real measured numbers.
GLM-130B on the Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 415k | 47.5-58 t/s | ~0.1-0.1 (slow) |
| Q8 | yes | 812k | 95-116.1 t/s | ~0.2-0.2 (slow) |
| Q4 | yes | 986k | 169.6-207.3 t/s | ~0.3-0.4 (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 Instinct MI455X run GLM-130B?▶
Yes. At Q4 it generates ~169.6-207.3 tok/s and fits up to 986k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.3-0.4 tok/s.
How much context fits?▶
At Q4, up to about 986k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
