Can the Huawei Ascend 950DT run GPT-2 (355M)?
Yes — here's how fast and up to what context, with real measured numbers.
GPT-2 (355M) on the Huawei Ascend 950DT
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1988k | 3662-4450.7 t/s | ~36.6-44.5 (slow) |
| Q8 | yes | 1993k | 7323.9-8901.4 t/s | ~73.2-89 (slow) |
| Q4 | yes | 1996k | 13078.5-15895.4 t/s | ~130.8-159 (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 Huawei Ascend 950DT run GPT-2 (355M)?▶
Yes. At Q4 it generates ~13078.5-15895.4 tok/s and fits up to 1996k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~130.8-159 tok/s.
How much context fits?▶
At Q4, up to about 1996k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
