NVIDIA · 80 GB HBM3 · 3350 GB/s bandwidth · Alibaba · 32.8B · model ctx up to 32K

✅ Yes — H100 80GB SXM5 (80 GB) can run Qwen2.5-Coder-32B-Instruct at Q4 (8K)
VRAM: 25.6 GB needed of 80 GB
Speed: ~65.0 tok/s (estimated)
SS · ExcellentComposite score: VRAM headroom × 0.5 + tok/s speed × 0.5. Q4 @ 8K context.
