Can V100 16GB PCIe run Qwen3.5-9B?

NVIDIA · 16 GB HBM2 · 900 GB/s bandwidth · Alibaba · 8.95B · model ctx up to 256K

✅ Yes — V100 16GB PCIe (16 GB) can run Qwen3.5-9B at Q4 (8K)
VRAM: 6.17 GB needed of 16 GB
Speed: ~108.1 tok/s (estimated)
SS · ExcellentComposite score: VRAM headroom × 0.5 + tok/s speed × 0.5. Q4 @ 8K context.
