Ranking updated on 09/10/2026
The RTX 4070 Ti (12 GB GDDR6X, 504 GB/s) tops out at 14B in Q4. Excellent for 7–14B models, but limits access to 24B+ models (which require 14+ GB).

-base : ollama run qwen2.5-coder:7b-base — it’s still the reference for this specific use case. ⚠️ Qwen 3.8: its reasoning is set very high by default and it “overthinks” simple requests — lower it to low (or turn it off) on first launch. ⚠️ License trap: Codestral 22B = Mistral Non-Production License → prohibited for coding at work. Qwen 3.5/3.8, Gemma 4, and Devstral are Apache 2.0. 💡 Running out of memory? Keep ~1.5 GB of VRAM free for context, or drop down one quantization level.🔌 To connect it to VS Code: Cline (multi-file agent), Aider (CLI) or Tabby/Twinny (FIM autocomplete) — they all connect to Ollama locally. The kit Local Copilot — ready-to-paste configs + tested setup — is available: /copilote-local.
Filter: Q4_K_M ≤ 11 GB. Bonus 7-14B (peak 12 GB). 504 GB/s = solid mid-range throughput.
Criteria considered:
The scoring is fully transparent: see our methodology for details on VRAM/tokens/sec calculations.
4070 Ti: Is 12 GB enough?
Yes for 7-14B in Q4. Mistral Nemo 12B Q5 (~9 GB) or Qwen 3 14B Q4 (~8 GB) run at 35-45 tok/s. For 24B, you need 16 GB: see 4070 Ti Super.
4070 Ti vs 4070 Super?
Even 12 GB GDDR6X 504 GB/s. The 4070 Ti has ~10% more CUDA cores. Marginal difference for LLMs. See RTX 4070 Super.
Which quantization for a 4070 Ti?
Q5_K_M for 7-8B (maximum quality, ~5 GB). Q4_K_M for 13-14B (Qwen 3 14B ~8 GB). Q6_K if possible for near-FP16 quality.
Is it worth it in 2026?
Used at ~€450, yes—solid mid-range LLM. New, prefer the 5070 (~€650), which benefits from GDDR7. See RTX 5070.
