Q4_K_S Qwen3.5 30B-A3B runs at around 29 t/s for me on the 370 version with 64 GB of RAM, running llama.cpp without any tweaking. I haven't tried Qwen3.6 yet, but could download it tomorrow; since I have a 128GB FW Desktop at home, I tend to use that remotely rather than my laptop directly, which preserves my battery.
