Reference performance data for heterogeneous speculative decoding with OpenVINO GenAI: a GPU
target model (Qwen3-14B INT4) paired with a small draft model (Qwen3-0.6B INT4) run on the CPU vs
the NPU vs the GPU, plus standalone draft-only throughput per device. Measured on a single Intel
Core Ultra 7 258V (Lunar Lake) laptop.
Headline: putting the draft on the NPU is a net slowdown (0.55–0.74×… See the full description on the dataset page:
