Can A100 80GB SXM4 run GLM-4.7-Flash?

NVIDIA · 80 GB HBM2e · 2039 GB/s bandwidth · Z.ai · 31.2B (active 3B) · MoE · model ctx up to 198K

Yes — the A100 80GB SXM4 (80 GB HBM2e) can run GLM-4.7-Flash. At Q4 with the default 8K context it needs ≈ 18.76 GB VRAM (weights 17.16 GB + KV cache 0.6 GB + 1 GB runtime overhead), which fits within 80 GB. Decode at Q4/8K: ≈ 432.5 tok/s (estimated, batch 1). FP16 (≈ 64.0 GB) also fits, at ≈ 118.9 tok/s (estimated). 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	18.46 GB	Yes	432.5 est.
Q4	8K default	18.76 GB	Yes	432.5 est.
Q4	32K	20.56 GB	Yes	432.5 est.
FP16	4K	63.7 GB	Yes	118.9 est.
FP16	8K default	64.0 GB	Yes	118.9 est.
FP16	32K	65.8 GB	Yes	118.9 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).
