Can the AMD Instinct MI455X run Gemma 1.1 7B Instruct?
Yes — here's how fast and up to what context, with real measured numbers.
Gemma 1.1 7B Instruct on the AMD Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2890k | 723-883.6 t/s | ~1.5-1.8 (slow) |
| Q8 | yes | 2956k | 1445.9-1767.2 t/s | ~3-3.6 (slow) |
| Q4 | yes | 2984k | 2582-3155.7 t/s | ~5.3-6.4 (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.
