Summary

User reports Gemma 4 E4B at 19.1 t/s generation and 920.7 t/s prompt processing on a Minisforum MS-S1 with an AMD Ryzen AI Max+ 395 (Strix Halo) and Radeon 8060S Graphics. Setup is llama.cpp with BF16 and flash attention, one CPU thread, batch and ubatch 2048, ngl 99, on Vulkan/RADV. The 19.07 t/s TG128 and 920.65 t/s PP2048 are separate synthetic llama-bench tests, not one 2048-in/128-out request; TG was not measured after the largest PP context.
