- Lucebox-native DFlash2 Qwen3.8-27B target. Task: count_to_30. One discarded warmup + three measured requests, median rates/timing; greedy decode (temperature omitted); target 27-token prompt -> 110 output tokens; 131072 context; batch 1. Target IQ4_XS GGUF with Q8_0 DFlash2 draft, DFlash2 spec-decode confirmed in server journal; identical output hashes across measured repetitions. Placement: Radeon 8060S iGPU (gfx1151) at PCIe 0000:c7:00.0, unified memory, weights streamed from system RAM; Q8 K/V cache. Peak VRAM is the maximum dflash_server DRM-client workload allocation (vram+gtt) on 0000:c7:00.0; power is peak observed GPU power. tokSOut uses server decode timing, tokSPrefill server prefill timing, tokSTotal client dispatch-to-DONE wall time.
