Ranking methodology

Filter: Q4_K_M ≤ 11 GB. Bonus: 7–14B (5070 peak) and 3–9B (perfectly smooth). GDDR7 bandwidth: 672 GB/s.

Criteria considered:

  • Q4_K_M ≤ 11 GB
  • Qwen 3 14B Q4 at full speed
  • Tokens/sec ≥ 60 on 7B
  • GDDR7 25% vs. 4070

The scoring is fully transparent: see our methodology for details on VRAM/tokens/sec calculations.

Frequently asked questions

RTX 5070 vs. 4070?

Same 12 GB. 5070 GDDR7 672 GB/s vs 4070 GDDR6X 504 GB/s = ~25% gain. Qwen 3 14B Q4: 5070 ~40 tok/s vs 4070 ~30 tok/s. See RTX 4070.

Is 12 GB enough for 2026 LLMs?

Yes for 7–14B in Q4_K_M. Mistral 7B, Qwen 3 8B/14B, Gemma 4 9B all excellent. For 24B+, you need 16 GB (RTX 5070 Ti). See RTX 5070 Ti.

RAG on RTX 5070?

Yes: Qwen 3 14B Q4 (~8 GB) + local ChromaDB + 32k context = ~11 GB used. Tight headroom, but usable. See RAG guide.

5070 or Mac mini M4 Pro 48 GB?

Mac mini = silence + 48 GB (comfortable for 24B + 24/7 server). 5070 = pure speed on 7–14B (40–60 tok/s). Choose based on usage. See Mac mini M4.
