What practitioners keep saying

The post reports Gemma 3 27B Q6_K at 20.0 tok/s generation and 391 tok/s prompt processing at 8192 tokens on an M5 Max 128GB machine.
That same result sits above the site's older M4 Max Q8_0 references, which turns Gemma 3 27B from single-tier evidence into a more credible high-end Apple buying signal.
