Summary
User reports Qwen3.8-27B at 53 tok/s mean decode on an Intel Arc Pro B60 24GB, with a 64K context window.
Setup is llama.cpp on the Vulkan backend with f16 KV cache, -ub 256 and a q8 draft KV cache, using DFlash2 speculative decoding and Intel's FA prefill kernel. Driver 32.0.101.8976 on Windows 11.
The user notes smaller cards (B580/B570/B50/A770) will not fit this 27B, though the Vulkan tuning applies. The same card also runs LTX-2.5 video generation via ComfyUI on XPU.
