Can V100 16GB PCIe run Qwen2.5-7B-Instruct?

NVIDIA · 16 GB HBM2 · 900 GB/s bandwidth · Alibaba · 7.6B · model ctx up to 128K

✅ Yes — V100 16GB PCIe (16 GB) can run Qwen2.5-7B-Instruct at Q4 (8K)
VRAM: 5.62 GB needed of 16 GB
Speed: ~127.3 tok/s (estimated)
SS · ExcellentComposite score: VRAM headroom × 0.5 + tok/s speed × 0.5. Q4 @ 8K context.
