The verdict

The RTX 4070 Ti (12 GB VRAM) handles Qwen3 30B-A3B comfortably using the Q4_K_M quantization, which fits in 20.0 GB. Expected throughput is around 0 tokens/second, which feels Cannot run — insufficient VRAM in interactive use. Mixture-of-Experts model with 30 B total parameters but only 3 B active per token. Runs at the speed of a 3 B model, with the knowledge of a 30 B. Sweet spot for 24 GB cards.

How to run it

1. Install Ollama or LM Studio.
2. Pull the Q4_K_M GGUF — best balance of quality and speed on 12 GB.
3. Start chatting. Expect ~0 tok/sec on first-token, faster after warmup.
