Can the AMD Radeon RX 9070 XT run Codestral Mamba?
Yes — here's how fast and up to what context, with real measured numbers.
Codestral Mamba on the AMD Radeon RX 9070 XT
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | yes | 45k | 55.7-68.1 t/s | ~3.5-4.2 (slow) |
| Q4 | yes | 70k | 99.4-121.5 t/s | ~6.2-7.5 (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 AMD Radeon RX 9070 XT run Codestral Mamba?▶
Yes. At Q4 it generates ~99.4-121.5 tok/s and fits up to 70k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~6.2-7.5 tok/s.
How much context fits?▶
At Q4, up to about 70k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
