Can the Intel Arc A770 16GB run LFM2.5-ColBERT-350M?
Yes — here's how fast and up to what context, with real measured numbers.
LFM2.5-ColBERT-350M on the Intel Arc A770 16GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 191k | 464-576 t/s | ~33.1-41.1 (slow) |
| Q8 | yes | 196k | 928-1152 t/s | ~66.3-82.3 (slow) |
| Q4 | yes | 199k | 1657.1-2057.1 t/s | ~118.4-146.9 (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 A770 16GB run LFM2.5-ColBERT-350M?▶
Yes. At Q4 it generates ~1657.1-2057.1 tok/s and fits up to 199k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~118.4-146.9 tok/s.
How much context fits?▶
At Q4, up to about 199k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
