Quick Answers
- How much VRAM does Qwen3 Coder 480B Q4 need?
- Qwen3 Coder 480B Q4 needs about 215GB minimum VRAM and 230GB optimal VRAM for a safer local run target.
- Can Qwen3 Coder 480B Q4 run on an RTX 3090 24GB?
- Not as a comfortable local target. Qwen3 Coder 480B Q4 needs about 215GB minimum and 230GB optimal VRAM, so cloud or larger local GPUs are safer.
- What is the Ollama command for Qwen3 Coder 480B Q4?
- Use ollama run qwen3-coder:480b. Check the Ollama tag qwen3-coder:480b before running.
- What is the approximate Ollama model size for Qwen3 Coder 480B Q4?
- Qwen3 Coder 480B Q4 uses the qwen3-coder:480b Ollama tag. Treat the Q4 480 profile as smaller than the runtime VRAM budget; use 215GB minimum VRAM and 230GB optimal VRAM as the safer sizing numbers.
- How much system RAM does Qwen3 Coder 480B Q4 need in Ollama?
- Plan for at least 128GB system RAM alongside 215GB minimum VRAM and 230GB optimal VRAM. More RAM helps if layers spill to CPU or if you run multiple models.
- What is the RAM vs VRAM requirement for Qwen3 Coder 480B Q4?
- Qwen3 Coder 480B Q4 should be sized by GPU VRAM first: 215GB minimum and 230GB optimal. System RAM should be at least 128GB so Ollama has room for CPU-side layers, context, and the surrounding app process.
- What is Qwen3 Coder 480B Q4 VRAM usage on an RTX 3090?
- Qwen3 Coder 480B Q4 is not recommended for an RTX 3090 24GB target. The page estimates 215GB minimum and 230GB optimal VRAM, with spill risk marked as high without a larger GPU or cloud.
- Which LocalVRAM profiles share the qwen3-coder:480b Ollama tag?
- LocalVRAM tracks these profiles for the same Ollama tag or model family: Qwen3 Coder 480B Q4 (Q4, 215GB min/230GB optimal); Qwen3 Coder 480B Q5 (Q5, 230GB min/232GB optimal); Qwen3 Coder 480B Q8 (Q8, 219GB min/229GB optimal); Qwen3 Coder 480B FP16 (FP16, 225GB min/237GB optimal); Qwen3 Coder 480B CLOUD (CLOUD, 215GB min/223GB optimal). Use the table on this page to compare quantization and VRAM targets before choosing a run command.
- Is Qwen3 Coder 480B Q4 benchmark data measured or estimated?
- Qwen3 Coder 480B Q4 currently uses estimated baseline anchors on this page. Verified benchmark data will replace the estimate after a local hardware run is available.
Ollama Model Size and RAM Notes
| Ollama tag | qwen3-coder:480b |
|---|---|
| Run command | ollama run qwen3-coder:480b |
| Model size guidance | Q4 quantization, 480 profile; size runtime by VRAM, not download size alone |
| Runtime VRAM target | 215GB minimum, 230GB optimal |
| System RAM planning | 128GB or more when running this tag locally with Ollama |
Download size alone is not a safe runtime budget. Runtime memory also includes KV cache, context length, and GPU layer placement.
Ollama RAM vs VRAM Requirements
| GPU VRAM usage estimate | 215GB minimum / 230GB optimal |
|---|---|
| System RAM requirement | 128GB or more for Ollama runtime headroom |
| RTX 3090 24GB fit | Not recommended |
| CPU spill risk | High without larger GPU or cloud |
| Context warning | Longer context increases KV cache memory, so real VRAM usage can exceed short-prompt estimates. |
For Ollama, VRAM is the first fit check. System RAM matters when layers spill to CPU, when context grows, or when the local app stack runs beside the model.
Available Tag Variants and VRAM Targets
| Profile | Quantization | VRAM target | Ollama tag |
|---|---|---|---|
| Qwen3 Coder 480B Q4 | Q4 | 215GB min / 230GB optimal | qwen3-coder:480b |
| Qwen3 Coder 480B Q5 | Q5 | 230GB min / 232GB optimal | qwen3-coder:480b |
| Qwen3 Coder 480B Q8 | Q8 | 219GB min / 229GB optimal | qwen3-coder:480b |
| Qwen3 Coder 480B FP16 | FP16 | 225GB min / 237GB optimal | qwen3-coder:480b |
| Qwen3 Coder 480B CLOUD | CLOUD | 215GB min / 223GB optimal | qwen3-coder:480b |
Ollama library tags often group multiple quantization choices under one model family. LocalVRAM separates them into VRAM profiles so you can pick the right local target.
