Can Desktop PC · Intel Arc B580 · 32 GB RAM run Qwen3 14B?

12 GB VRAM + 32 GB RAM · 456 GB/s memory bandwidth · Qwen3 14B has 14.8B parameters.

Short answer

Yes, excellent for chat; borderline for coding questions.

Best quantization for chat: Q3_K_M (6.8 GB of weights) on LM Studio. Generation: 30–40 tok/s, leaving about 1.9 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 estimates calibrated against measured benchmarks on similar hardware. “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 8K 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=8192 before `ollama serve` for long prompts.
