Yes — here's how fast and up to what context, with real measured numbers.
ProBERTa on the AMD Instinct MI300X 192GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2671k | 37943.2-46375 t/s | ~286.4-350 (slow) |
| Q8 | yes | 2672k | 75886.4-92750 t/s | ~572.7-700 (slow) |
| Q4 | yes | 2672k | 135511.4-165625 t/s | ~1022.7-1250 (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.
