ROCM

Yes — the Ryzen AI Max+ 395 128GB (96 GB LPDDR5X) can run Qwen3.5-122B-A10B. At Q4 with the default 8K context it needs ≈ 68.35 GB VRAM (weights 67.1 GB + KV cache 0.25 GB + 1 GB runtime overhead), which fits within 96 GB. Decode at Q4/8K: ≈ 13.7 tok/s (estimated, batch 1). FP16 needs ≈ 245.25 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	68.23 GB	Yes	13.7 est.
Q4	8K default	68.35 GB	Yes	13.7 est.
Q4	32K	69.1 GB	Yes	13.7 est.
FP16	4K	245.12 GB	No	1.6 est.
FP16	8K default	245.25 GB	No	1.6 est.
FP16	32K	246.0 GB	No	1.6 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).
