Reported by the source; GPU count, offloading and concurrent requests can change these figures. Prompt-processing speed is input throughput, not time to first token. Check the full setup before comparing.

User reports Llama 4 Scout 17B-16E at 20.2 t/s generation and 225 t/s prompt processing on an AMD Strix Halo 128GB machine. Setup is llama.cpp Vulkan on the Radeon 8060S iGPU with Q4_K_XL, 6 threads and maximum GPU offload. The figures come from separate llama-bench phase tests, a 512-token prompt and 128-token generation, not an end-to-end rate; rates are rounded and context depth, KV precision and batch settings are unreported.
