Can Desktop PC · GeForce RTX 4090 · 32 GB RAM run Qwen2.5-Coder 32B Instruct?
24 GB VRAM + 32 GB RAM · 1008 GB/s memory bandwidth · Qwen2.5-Coder 32B Instruct has 32.8B parameters.
Short answer
Yes, excellent for chat; borderline for coding in a repository.
Best quantization for chat: Q4_K_M (19 GB of weights) on Ollama. Generation: 30–40 tok/s, leaving about 1.0 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.
