Q: How fast is qwen3 30B-A3B MoE on the NVIDIA Titan V 12GB?

~160–270 tok/s (active-expert estimate) on the NVIDIA Titan V 12GB. computed roofline: 652.8 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
