Can the Jetson Thor T2000 run OPT-2.7B (finetuned on WT2)?
Yes — here's how fast and up to what context, with real measured numbers.
OPT-2.7B (finetuned on WT2) on the Jetson Thor T2000
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 114k | 18.5-22.1 t/s | ~1.4-1.6 (slow) |
| Q8 | yes | 156k | 37-44.1 t/s | ~2.7-3.2 (slow) |
| Q4 | yes | 174k | 66.1-78.8 t/s | ~4.8-5.8 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
