Can A100 80GB SXM4 run Qwen3-235B-A22B-Instruct-2507?

NVIDIA · 80 GB HBM2e · 2039 GB/s bandwidth · Alibaba · 235.1B (active 22B) · MoE · model ctx up to 256K

No — Qwen3-235B-A22B-Instruct-2507 at Q4 needs ≈ 132.5 GB even at 4K context, beyond the A100 80GB SXM4's 80 GB HBM2e. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 59.4 tok/s (estimated, batch 1). FP16 needs ≈ 475.6 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	132.5 GB	No	61.4 est.
Q4	8K default	134.71 GB	No	59.4 est.
Q4	32K	147.91 GB	No	49.3 est.
FP16	4K	473.4 GB	No	—
FP16	8K default	475.6 GB	No	—
FP16	32K	488.8 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).
