- Current best valid Qwen3.6 27B INT4 AutoRound fresh-response row on one Intel Arc Pro B70 for the webhie AutoRound + runtime INT8 target LM-head BF16-scale + runtime INT4 draft LM-head ReplaySSM recipe. Same recipe as the approved 67.519 tok/s row, now fully quality-confirmed at 68.236 tok/s; treat as a small variance-sensitive current-confirm record, not a new mechanism. Fixed realistic suite, each prompt once cold, cached_tokens=0 on every request, no prompt/KV/cache/history/ngram/response reuse, repeat64 quality matched baseline.
