Can the Apple M2 Ultra 192GB run (ensemble): AWD-LSTM-DOC (fin) × 5 (WT2)?
Yes — here's how fast and up to what context, with real measured numbers.
(ensemble): AWD-LSTM-DOC (fin) × 5 (WT2) on the Apple M2 Ultra 192GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2608k | 1470.3-1773 t/s | ~18.4-22.2 (slow) |
| Q8 | yes | 2611k | 2940.5-3545.9 t/s | ~36.8-44.3 (slow) |
| Q4 | yes | 2612k | 5251-6332 t/s | ~65.6-79.2 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
FAQ
Can the Apple M2 Ultra 192GB run (ensemble): AWD-LSTM-DOC (fin) × 5 (WT2)?▶
Yes. At Q4 it generates ~5251-6332 tok/s and fits up to 2612k context; beyond that it spills to SSD swap and slows to ~65.6-79.2 tok/s.
How much context fits?▶
At Q4, up to about 2612k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
