Can Laptop · GeForce RTX 4090 Laptop · 32 GB RAM run Qwen3 14B?

16 GB VRAM + 32 GB RAM · 576 GB/s memory bandwidth · Qwen3 14B has 14.8B parameters.

Short answer

Yes, excellent for chat; borderline for coding in a repository.

Best quantization for chat: Q5_K_M (9.9 GB of weights) on Ollama. Generation: 25–45 tok/s, leaving about 2.9 GB free for your other apps.

How it rates for each workload

Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.

Speeds are bandwidth-based estimates; no direct benchmark exists for this pair. “First reply” is the time to read the workload’s opening prompt. How we calculate

Get it running

Copy-paste commands for the Q3_K_M build with a 32K context. Ollama and llama.cpp download the file straight from Hugging Face.

ollama run hf.co/unsloth/Qwen3-14B-GGUF:Q3_K_M

Downloads 7.32 GB (Q3_K_M). Ollama's default context is small: set OLLAMA_CONTEXT_LENGTH=32768 before `ollama serve` for long prompts.
