Can the Intel Arc B580 12GB run LDM-1.45B?
Yes — here's how fast and up to what context, with real measured numbers.
LDM-1.45B on the Intel Arc B580 12GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 101k | 91.2-113.2 t/s | ~8-9.9 (slow) |
| Q8 | yes | 123k | 182.4-226.4 t/s | ~16-19.9 (slow) |
| Q4 | yes | 133k | 325.7-404.3 t/s | ~28.6-35.5 (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 Intel Arc B580 12GB run LDM-1.45B?▶
Yes. At Q4 it generates ~325.7-404.3 tok/s and fits up to 133k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~28.6-35.5 tok/s.
How much context fits?▶
At Q4, up to about 133k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
