Can Mac Studio M2 Ultra 192GB run Qwen3-30B-A3B-Instruct-2507?

Apple · 192 GB LPDDR5 · 800 GB/s bandwidth · Alibaba · 30.5B (active 3B) · MoE · model ctx up to 256K

Yes — the Mac Studio M2 Ultra 192GB (192 GB LPDDR5) can run Qwen3-30B-A3B-Instruct-2507. At Q4 with the default 8K context it needs ≈ 18.38 GB VRAM (weights 16.78 GB + KV cache 0.6 GB + 1 GB runtime overhead), which fits within 192 GB. Decode at Q4/8K: ≈ 169.7 tok/s (estimated, batch 1). FP16 (≈ 62.6 GB) also fits, at ≈ 46.7 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	18.08 GB	Yes	169.7 est.
Q4	8K default	18.38 GB	Yes	169.7 est.
Q4	32K	20.18 GB	Yes	169.7 est.
FP16	4K	62.3 GB	Yes	46.7 est.
FP16	8K default	62.6 GB	Yes	46.7 est.
FP16	32K	64.4 GB	Yes	46.7 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).
