Can Surface Laptop Ultra · RTX Spark N1X (20-core) · 128 GB run Qwen2.5-Coder 32B Instruct?

128 GB unified · 300 GB/s memory bandwidth · Qwen2.5-Coder 32B Instruct has 32.8B parameters.

Short answer

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

Best quantization for chat: Q5_K_M (22 GB of weights) on Ollama. Generation: 6–10 tok/s, leaving about 91 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 Q5_K_M build with a 32K context. Ollama and llama.cpp download the file straight from Hugging Face.

ollama run hf.co/unsloth/Qwen2.5-Coder-32B-Instruct-GGUF:Q5_K_M

Downloads 23.26 GB (Q5_K_M). Ollama's default context is small: set OLLAMA_CONTEXT_LENGTH=32768 before `ollama serve` for long prompts.
