Can the Intel Arc A770 16GB run MegaMolBART?
Yes — here's how fast and up to what context, with real measured numbers.
MegaMolBART on the Intel Arc A770 16GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 200k | 3608.9-4480 t/s | ~257.8-320 (slow) |
| Q8 | yes | 201k | 7217.8-8960 t/s | ~515.6-640 (slow) |
| Q4 | yes | 201k | 12888.9-16000 t/s | ~920.6-1142.9 (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 MegaMolBART?▶
Yes. At Q4 it generates ~12888.9-16000 tok/s and fits up to 201k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~920.6-1142.9 tok/s.
How much context fits?▶
At Q4, up to about 201k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
