RTX A3000 Laptop GPU strengths and weaknesses

Strengths

  • Runs 7–9B models: Qwen3.5 9B at 39.6 tok/s in 5.8 GB
  • Reads long prompts fast: A 4K-token prompt on Qwen3.5 4B starts answering in 1.7 s
  • Low power draw: 130 W board power; a 300 W PSU is enough

Weaknesses

  • 14B models don't fit: Qwen3 14B needs 11.9 GB at Q4 vs 6 GB here
  • Little room for context: Qwen3.5 9B uses 5.8 of 6 GB, 0.2 GB left
  • No FP8 or NVFP4: Ampere predates both; use GGUF, AWQ or GPTQ builds
