Memory math: weights + context vs budget
Weights take 11 GB. Context costs extra KV-cache on top — this is where long-context sessions break on cards that technically fit the weights.
KV-cache figures assume an fp16 cache, the llama.cpp/Ollama default. Standard GQA models use a size-class estimate (8 KV heads x 128 head dim class); hybrid linear-attention models (Qwen3.5/3.6, Qwen3-Next) use the exact per-token cost from their published config, since only their sparse full-attention layers cache KV. A q8_0 KV cache roughly halves either figure. Estimates, not measurements.
Qwen3 14B on RTX 5070 Ti: FAQ
Can the NVIDIA GeForce RTX 5070 Ti run Qwen3 14B?
Yes. Qwen3 14B (Q4_K_M) loads in about 11 GB and the RTX 5070 Ti offers 14.4 GB of usable VRAM, leaving headroom for context. Expect at roughly 54 tokens/sec (est.).
How much VRAM does Qwen3 14B need?
About 11 GB for the weights at Q4_K_M, plus KV-cache for context: roughly 3.0 GB extra at 16k tokens. The RTX 5070 Ti budget is 14.4 GB (16 GB x 90%).
What is the best quantization of Qwen3 14B for the RTX 5070 Ti?
Stick with the Q4_K_M build at 11 GB — every heavier quant exceeds the 14.4 GB usable VRAM.
What GPU do I need to run Qwen3 14B comfortably?
The RTX 5070 Ti already runs Qwen3 14B comfortably. Larger cards only buy you longer context or a heavier quant.
