Can I Run Nemotron 3 Super on MacBook Pro 16" (M4 Max, 128 GB)?

Yes, but it is tight

Yes, but it is tight — Nemotron 3 Super 120B-A12B at Q5_K_M needs about 88.7 GB of the 96 GB usable on MacBook Pro 16" (M4 Max, 128 GB), leaving only ~7.3 GB before the runtime starts swapping. Expect ~27.6 tok/s (estimated), with room for about 16,384 tokens of context.

Confidence: low · Recommended quantization: Q5_K_M · Estimated speed: ~27.6 tok/s

What to watch out for

This model does not publish its full attention configuration, so the KV-cache share of these figures is inferred from its parameter count rather than computed exactly.
Memory on this machine is not upgradeable, so the configuration you buy is the ceiling for every model you will ever run on it.

MacBook Pro M4 Max 128 GB limitations

Unified memory is soldered — the 128 GB decision is permanent and cannot be upgraded later.
Sustained decode speed on battery is materially below the plugged-in figures quoted here.

Recommended setup

Ollama or LM Studio (Metal) — MLX for the fastest Apple-native throughput

How these numbers are calculated

Memory need = quantized weights + KV cache at 8,192 tokens (f16) + 0.8 GB runtime overhead.
128 GB unified memory at 546 GB/s, shared between CPU and GPU.
macOS reserves a share of unified memory for the system, so not all of it is available to a model.
Throughput is a memory-bandwidth roofline estimate, not a measurement. It is labelled "estimated" everywhere it appears.
KV cache is inferred from the parameter count because this model does not publish its full attention configuration.
