Can the Intel Arc Pro B50 run Refact-1.6B?
Yes — here's how fast and up to what context, with real measured numbers.
Refact-1.6B on the Intel Arc Pro B50
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 153k | 40.6-50.4 t/s | ~7.3-9 (slow) |
| Q8 | yes | 177k | 81.2-100.8 t/s | ~14.5-18 (slow) |
| Q4 | yes | 188k | 145-180 t/s | ~25.9-32.1 (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 Pro B50 run Refact-1.6B?▶
Yes. At Q4 it generates ~145-180 tok/s and fits up to 188k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~25.9-32.1 tok/s.
How much context fits?▶
At Q4, up to about 188k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
