Yes. Qwen3-14B at Q4_K_M needs about 11.3 GB, and the GeForce RTX 5070 Ti has 16.0 GB usable at a ~4k context.

Can I run Qwen3-14B on an RTX 5070 Ti?

Qwen3-14B at Q4_K_M needs about 11.3 GB, and the GeForce RTX 5070 Ti has 16.0 GB usable. That figure is 16 GB of VRAM on the spec sheet, of which 16.0 GB is usable for weights and cache, at 896 GB/s memory bandwidth. Alibaba’s 14B Qwen3. It sits in the sweet spot for 12–16 GB cards that want more quality than an 8B. These are estimates from our formula, not measured benchmarks.

Estimated tokens per second

Estimate: 60–85 tokens/sec at Q4_K_M. This is a bandwidth-derived range, not a bench. Efficiency is a 60–85% GPU band from How we calculate.

Context headroom

At Q4_K_M, this machine has headroom out to about 32k tokens under our KV estimate. Longer chats need more memory for the cache. Figures assume an FP16 KV cache.
