Can H200 141GB SXM5 run Qwen3.5-122B-A10B?

NVIDIA · 141 GB HBM3e · 4800 GB/s bandwidth · Alibaba · 122.0B (active 10.0B) · MoE · model ctx up to 256K

Yes — the H200 141GB SXM5 (141 GB HBM3e) can run Qwen3.5-122B-A10B. At Q4 with the default 8K context it needs ≈ 70.1 GB VRAM (weights 67.1 GB + KV cache 2.0 GB + 1 GB runtime overhead), which fits within 141 GB. Decode at Q4/8K: ≈ 305.5 tok/s (estimated, batch 1). FP16 needs ≈ 247.0 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	69.1 GB	Yes	305.5 est.
Q4	8K default	70.1 GB	Yes	305.5 est.
Q4	32K	76.1 GB	Yes	305.5 est.
FP16	4K	246.0 GB	No	78.8 est.
FP16	8K default	247.0 GB	No	78.2 est.
FP16	32K	253.0 GB	No	74.5 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).
