A practitioner ran Nemotron-3 Super (Q4_K_M), GPT-OSS 120B (MXFP4), and Qwen3.5 122B (Q4_K_M) on M5 Max 128GB and found Nemotron-3 Super wins on both quality and speed, with GPT-OSS 120B second and Qwen3.5 122B third. The post (52up, 52cmts — 1.0 comment-to-score ratio indicating deep technical engagement) is the first published three-way benchmark for the M5 Max against this generation of 120B models, giving local builders a concrete hardware/model pairing guide.
