Summary

User reports Qwen3.6-35B-A3B at 59.6 t/s generation and 1029 t/s prompt processing on a single Radeon 8060S iGPU in an AMD Strix Halo system with 128 GB unified memory. Setup is llama-bench with the Unsloth UD-Q4_K_XL quant, full offload, batch 2048 and flash attention; the 20.8 GiB figure is artifact size, not measured resident memory. The rates are separate 512-token prompt and 128-token generation microbenchmarks, not one end-to-end request, and no TTFT is reported.
