Can the AMD Radeon RX 9070 XT run Gemma 3 QAT 1B?
Yes — here's how fast and up to what context, with real measured numbers.
Gemma 3 QAT 1B on the AMD Radeon RX 9070 XT
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 171k | 202.9-247.9 t/s | ~12.6-15.4 (slow) |
| Q8 | yes | 186k | 405.7-495.9 t/s | ~25.2-30.8 (slow) |
| Q4 | yes | 193k | 724.5-885.5 t/s | ~45-55 (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.
