Q: How fast is qwen3-coder 30B-A3B MoE on the RTX 3070 Laptop?

~110–180 tok/s (active-expert estimate) on the RTX 3070 Laptop. computed roofline: 448 GB/s × 0.46–0.76 efficiency window / 1.9GB (Q4_K_M) — bands, never points. MoE: file is 18.6GB (that decides fit) but only ~3B of experts activate per token (~1.9GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math

Question 1

Can the RTX 3070 Laptop run qwen3-coder 30B-A3B MoE?

Accepted Answer

qwen3-coder 30B-A3B MoE needs about 18.98GB working set (weights 18.6GB + KV cache 0.38GB at 4k context). The RTX 3070 Laptop offers ~8GB usable — verdict: no. 19.0 GB vs 8 GB usable — does not fit
