VRAM Requirements: Which Card Runs Which Model

The choice between these three models is primarily a VRAM decision. At Q4_K_M quantization: Llama 3.3 8B uses 4.9 GB, Qwen 3 14B uses 9.3 GB, and Mistral Small 3.1 24B uses 14.4 GB. This maps directly onto three GPU tiers: 6–8 GB cards (Llama 3.3 8B only), 10–12 GB cards (Qwen 3 14B), and 16+ GB cards (Mistral Small 24B).

Speed on RTX 4090 at Q4_K_M: Llama 3.3 8B runs at approximately 45 tok/s, Qwen 3 14B at ~28 tok/s, and Mistral Small 3.1 24B at ~20 tok/s. On an RTX 3060 12 GB, only Llama 3.3 8B and Qwen 3 14B fit β€” Mistral Small 24B requires at minimum a 16 GB card to avoid spilling to CPU RAM.

The benchmark spread is meaningful: Mistral Small 24B's 81% MMLU is 14 points above Llama 3.3 8B and 6 points above Qwen 3 14B. On complex multi-step reasoning and instruction-following tasks, this gap is noticeable in practice.

Quality vs VRAM: When Each Model Wins

Llama 3.3 8B wins on VRAM efficiency. At 4.9 GB Q4_K_M it is the only model in this group that fits a 6 GB card with headroom for a 4k token context window. It scores 66.6% on MMLU and delivers snappy interactive responses (~45 tok/s on RTX 4090). For chat, quick coding queries, and daily use on constrained hardware, it is the correct pick.

Qwen 3 14B wins at 12 GB VRAM. Its 74.8% MMLU places it well above Llama 3.3 8B on reasoning and coding β€” and it fits within the most common prosumer GPU tier. The Qwen Coder 14B variant (same size, code-tuned) scores approximately 78% on HumanEval. If your primary use is coding and you have a 12 GB card, Qwen 3 14B is the answer.

Mistral Small 3.1 24B wins on quality when VRAM allows. Its 81% MMLU and strong multilingual performance make it the top choice for 16 GB cards. It handles long-form reasoning, structured output tasks, and complex instruction sets more reliably than the 14B-class models. On an RTX 4090 24 GB it fits at Q5_K_M for even better quality.

Quick Answers: Mistral Small 24B vs Qwen 14B vs Llama 8B

Can Mistral Small 24B run on an RTX 3060 12 GB?β–Ύ
No. Mistral Small 3.1 24B at Q4_K_M requires 14.4 GB VRAM, exceeding the RTX 3060 12 GB. Dropping to Q2_K brings it to approximately 7.6 GB but causes significant quality degradation. For RTX 3060 12 GB, Qwen 3 14B Q4_K_M (9.3 GB) is the correct choice β€” it leaves 2.7 GB headroom for context.
Is Mistral Small 24B better than Qwen 3 14B for coding?β–Ύ
For general coding, Mistral Small 24B has a slight edge due to its larger size. However, Qwen 3 Coder 14B (the code-tuned Qwen variant) is competitive with Mistral Small 24B on HumanEval and fits in 12 GB VRAM. If your budget is a 16 GB card and you need both reasoning and coding, Mistral Small 24B wins. On 12 GB, Qwen Coder 14B is the better tradeoff.
Which model should I use on a 16 GB GPU like the RTX 4080?β–Ύ
Mistral Small 3.1 24B Q4_K_M at 14.4 GB fits with 1.6 GB headroom β€” enough for a 2k context window. It outperforms Qwen 3 14B on reasoning benchmarks. Alternatively, Qwen 3 32B at Q3_K_M fits in approximately 13.5 GB and competes with Mistral Small 24B on coding tasks while offering more parameters.
How does Llama 3.3 8B compare to Llama 3.2?β–Ύ
Llama 3.2 8B was not released β€” the 3.2 series introduced 1B, 3B, and multimodal 11B/90B variants only. Llama 3.3 8B remains the standard 8B Llama reference model. For text-only use at 6–8 GB VRAM, Llama 3.3 8B is the current recommended pick in this size class.
