Qwen3-Coder 80B-A3B (MoE) — VRAM, Speed & Local Setup

Efficiency flagship. 80B total with only 3B active parameters per forward pass. Scores 76.4 on SWE-bench Pro — comparable to Claude Sonnet 4.5 — while staying light enough to self-host on a single high-VRAM card. Beats DeepSeek V3.2 on most coding benchmarks.

Qwen3-Coder 80B-A3B (MoE) needs about 49 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache. On Apple Silicon that figure comes out of unified memory.

VRAM and Speed by Quantization

Modelled on a reference NVIDIA RTX 4090 (24 GB). Weights plus framework overhead only — this model publishes no architecture we can read, so no KV cache is included. A real session needs more; the figure is a floor, not a target. Speed figures are ESTIMATES from the memory-bandwidth roofline described on the methodology page, not benchmarks we ran — rows marked measured come from published or reader-submitted runs. VRAM here includes the KV cache, so it reads higher than the headline figure above, which does not.

Qwen3-Coder 80B-A3B (MoE) — Frequently Asked Questions

How much VRAM does Qwen3-Coder 80B-A3B (MoE) need?
About 49 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.
Does Qwen3-Coder 80B-A3B (MoE) run on an RTX 4090 (24 GB)?
No. Qwen3-Coder 80B-A3B (MoE) needs about 49 GB at Q4_K_M, more than a single RTX 4090's 24 GB. It needs a larger card, several GPUs, or Apple Silicon with enough unified memory — or it runs with part of the weights offloaded to system RAM, which is much slower.
How do I run Qwen3-Coder 80B-A3B (MoE) locally?
Install Ollama and run `ollama run qwen3-coder:80b-a3b-q4`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
What other sizes does Qwen3-Coder come in?
Qwen3-Coder 8B (6 GB), Qwen3-Coder 80B-A3B (MoE) (49 GB), Qwen3-Coder 480B-A35B (MoE) (291 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
