Can the FuriosaAI RNGD run Mamba 2, 2.7B?
Yes — here's how fast and up to what context, with real measured numbers.
Mamba 2, 2.7B on the FuriosaAI RNGD
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 569k | 180.6-219.4 t/s | ~4.8-5.9 (slow) |
| Q8 | yes | 610k | 361.1-438.9 t/s | ~9.6-11.7 (slow) |
| Q4 | yes | 628k | 644.8-783.7 t/s | ~17.2-20.9 (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 FuriosaAI RNGD run Mamba 2, 2.7B?▶
Yes. At Q4 it generates ~644.8-783.7 tok/s and fits up to 628k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~17.2-20.9 tok/s.
How much context fits?▶
At Q4, up to about 628k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
