Can V100 16GB PCIe run Qwen3.5-27B?

NVIDIA · 16 GB HBM2 · 900 GB/s bandwidth · Alibaba · 27.0B · model ctx up to 256K

❌ No — Qwen3.5-27B Q4 needs 16.1 GB, card only has 16 GB
VRAM: 16.1 GB needed of 16 GB
Speed: ~57.9 tok/s (estimated)
FF · No FitComposite score: VRAM headroom × 0.5 + tok/s speed × 0.5. Q4 @ 8K context.

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).
