Qwen3.8 27B

User reports Qwen3.8 27B at 509 t/s prompt processing on one AMD Strix Halo APU/iGPU, named as Ryzen AI Max+ 395 with Radeon 8060S. Setup is the 1bit engine lean ROCm build with Q4_0-H32 W4A4 and a 32-point Walsh-Hadamard-rotated activation path, run through native llama-bench pp512 at microbatch 512. The figure is prompt-processing only; generation is left blank because the card's roughly 11 tok/s and a later site's roughly 13 tok/s lack a matched native tg128 measurement. Context capacity, iteration count and memory are unreported.
