Can MacBook Pro M3 Max 128GB run Qwen3.6-27B?

Apple · 128 GB LPDDR5 · 400 GB/s bandwidth · Alibaba · 27.8B · model ctx up to 256K

Yes — the MacBook Pro M3 Max 128GB (128 GB LPDDR5) can run Qwen3.6-27B. At Q4 with the default 8K context it needs ≈ 21.85 GB VRAM (weights 15.29 GB + KV cache 5.56 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 9.2 tok/s (estimated, batch 1). FP16 (≈ 62.16 GB) also fits, at ≈ 2.5 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	19.07 GB	Yes	9.2 est.
Q4	8K default	21.85 GB	Yes	9.2 est.
Q4	32K	38.53 GB	Yes	9.2 est.
FP16	4K	59.38 GB	Yes	2.5 est.
FP16	8K default	62.16 GB	Yes	2.5 est.
FP16	32K	78.84 GB	Yes	2.5 est.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s means the model is far beyond this card (offload-only territory).
