Speculative Decoding Benchmark (RTX 4090)

Speculative Decoding Benchmark — RTX 4090 TL;DR: 4,576 benchmark runs measuring speculative decoding speedup / acceptance rate across llama.cpp and LM Studio, Qwen3 (8B/14B) and Llama-3.1-8B target models, on a single consumer RTX 4090 (24GB). Best observed case: the draft-free ngram-mod self-speculative mode on structured tasks (JSON extraction 2.81x, code 2.76x, global-median aggregation at temp=0). Open-ended tasks (creative writing, translation) with a traditional draft… See the full description on the dataset page: huggingface.co/datasets/steven0226/speculative-decoding-bench-rtx4090.
