-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 ≤ 14 GB. Bonus: 7-14B and 13-24B. 512 GB/s + ROCm 6.
Criteria considered:
The scoring is fully transparent: see our methodology for details on VRAM/tokens/sec calculations.
RX 6800 XT in 2026: usable LLM?
Yes — ROCm 6 supports RDNA 2. 16 GB + 512 GB/s = Mistral Small 24B Q4 at 18 tok/s, Qwen 3 14B Q5 at 28 tok/s. See guide.
RX 6800 XT vs. RTX 3080 used 10 GB?
6800 XT = 16 GB + 512 GB/s vs 3080 = 10 GB + 760 GB/s. AMD has +6 GB VRAM (unlocks 24B). NVIDIA ~50% faster on 7-9B. Depends on your priority. See RTX 3080.
6800 XT price in France?
~€300–400 used. Excellent €/GB of VRAM value for LLMs if you accept ROCm.
Should you prefer a new 7800 XT?
7800 XT = the same 16 GB + 624 GB/s + RDNA 3 (~€500). Faster and more modern. Depending on your budget. See RX 7800 XT.
