Can Ryzen AI Max+ 395 128GB run MiniMax-M3?

AMD · 96 GB LPDDR5X · 215 GB/s bandwidth · MiniMax · 428.0B (active 23.0B) · MoE · model ctx up to 1024K

ROCM

No — MiniMax-M3 at Q4 needs ≈ 238.7 GB even at 4K context, beyond the Ryzen AI Max+ 395 128GB's 96 GB LPDDR5X. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 2.7 tok/s (estimated, batch 1). FP16 needs ≈ 861.6 GB — does not fit on this card. 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	238.7 GB	No	2.7 est.
Q4	8K default	241.0 GB	No	2.7 est.
Q4	32K	254.8 GB	No	2.4 est.
FP16	4K	859.3 GB	No	—
FP16	8K default	861.6 GB	No	—
FP16	32K	875.4 GB	No	—

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).
