ROCM

Yes — the Ryzen AI Max+ 395 128GB (96 GB LPDDR5X) can run NVIDIA-Nemotron-3-Super-120B-A12B-BF16. At Q4 with the default 8K context it needs ≈ 67.12 GB VRAM (weights 66.0 GB + KV cache 0.12 GB + 1 GB runtime overhead), which fits within 96 GB. Decode at Q4/8K: ≈ 11.4 tok/s (estimated, batch 1). FP16 needs ≈ 241.12 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	67.06 GB	Yes	11.4 est.
Q4	8K default	67.12 GB	Yes	11.4 est.
Q4	32K	67.48 GB	Yes	11.4 est.
FP16	4K	241.06 GB	No	1.4 est.
FP16	8K default	241.12 GB	No	1.4 est.
FP16	32K	241.48 GB	No	1.4 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).
