User reports Qwen3.8-27B at 53.3 tok/s per-request decode (47 to 58 across eight requests) on an Intel Arc Pro B60 24GB. Setup is llama.cpp Vulkan build b11524 with Q4_K_M and an F16 KV cache, a DFlash2 draft model, one request at a time, 32K context, the whole model on the card. The repo's 42.3 tok/s headline is wall-clock eval-suite throughput with prompt processing included, not a decode rate; stock llama.cpp with no drafter gave 16 tok/s in llama-bench tg32. Prompt reading at 32K was 420 tok/s with the Intel FA kernel, versus 118 tok/s stock.
