Can the Intel Arc Pro B70 run DARTS (second order) (PTB)?
Yes — here's how fast and up to what context, with real measured numbers.
DARTS (second order) (PTB) on the Intel Arc Pro B70
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 426k | 7666.1-9516.5 t/s | ~504.3-626.1 (slow) |
| Q8 | yes | 426k | 15332.2-19033 t/s | ~1008.7-1252.2 (slow) |
| Q4 | yes | 426k | 27378.9-33987.6 t/s | ~1801.2-2236 (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 B70 run DARTS (second order) (PTB)?▶
Yes. At Q4 it generates ~27378.9-33987.6 tok/s and fits up to 426k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1801.2-2236 tok/s.
How much context fits?▶
At Q4, up to about 426k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
