Qwen3 Coder-Next-80B / Vulkan RADV native PP512/TG128
on AMD Strix Halo 128GB · llama.cpp / Vulkan RADV / build unknown
Summary
User reports Qwen3-Coder-Next-80B at 40 t/s generation and 586 t/s prompt processing on a single Radeon 8060S iGPU in an AMD Strix Halo system with 128 GB unified memory.
Setup is llama.cpp with the MXFP4 quant, full offload, batch 2048 and flash attention, using the RADV Vulkan backend.
The figures are separate 512-token prompt and 128-token generation microbenchmarks, not one end-to-end request; the source notes post-hoc MXFP4 can underperform conventional quants.
