Can Desktop PC · GeForce RTX 4060 Ti 16GB · 32 GB RAM run Qwen3-Coder 30B-A3B Instruct?
16 GB VRAM + 32 GB RAM · 288 GB/s memory bandwidth · Qwen3-Coder 30B-A3B Instruct has 30.5B parameters (3.3B active per token).
Short answer
It loads, but it's borderline even for chat.
Best quantization for chat: Q4_K_M (17 GB of weights) on Ollama. Generation: 30–45 tok/s, leaving about 0.0 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.

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
