Key Takeaways
- Same VRAM: both 7B models need 5.5 GB at Q4_K_M; both 32B need 20.5 GB
- Math: DeepSeek-R1-Distill-Qwen-32B wins (94% MATH-500 vs 90.3%)
- Code: Qwen2.5-Coder 32B wins (91.5% HumanEval vs 83%)
- Chinese: Qwen2.5 wins — native tokenisation, 30–40% more efficient on CJK text
- Reasoning chains: DeepSeek-R1 distills produce long chain-of-thought by default
- General chat: Qwen2.5 14B is slightly more fluent; DeepSeek 14B distill tends to over-reason

Which Model to Run at Each Hardware Tier
VRAM requirements are identical between the two families at each parameter size. The choice between DeepSeek and Qwen is a task preference, not a hardware constraint.
- 8 GB VRAM (RTX 3060 / M2 16 GB): Qwen2.5 7B for coding/chat; DS-R1-Distill-Qwen-7B for math tutoring
- 12 GB VRAM (RTX 3080 / M2 Pro 24 GB): Qwen2.5 14B for general use; DS-R1-Distill-Qwen-14B for reasoning chains
- 24 GB VRAM (RTX 4090 / M3 Max 48 GB): Qwen2.5-Coder 32B or Qwen2.5 32B — best all-round local model in this tier
- 48 GB+ (M2/M3 Ultra / dual RTX 4090): Qwen2.5 72B (86.1% MMLU, 97% HumanEval) — near GPT-4 class
- CPU-only (32+ GB RAM): Qwen2.5 7B or DS-R1-Distill 7B — both run at 3–8 tok/s on modern laptop CPUs
DeepSeek Local Models Explained
DeepSeek released its R1 reasoning model as a full 671B MoE (mixture-of-experts) architecture that requires server-grade hardware. For consumer local use, the practical option is the distilled versions — smaller dense models trained to replicate R1's chain-of-thought reasoning.
- DeepSeek-R1-Distill-Qwen-7B: 5.5 GB VRAM at Q4_K_M. Strongest math model at the 7B tier (88% MATH-500). Produces long reasoning chains; disable chain-of-thought via system prompt for faster chat.
- DeepSeek-R1-Distill-Qwen-14B: 9.5 GB VRAM. Best reasoning-per-VRAM at the 14B tier. Good for math tutoring, logic puzzles, and structured analysis tasks.
- DeepSeek-R1-Distill-Qwen-32B: 20.5 GB VRAM. Highest MATH-500 score of any consumer-runnable model at 94%. Use when math accuracy is the priority over coding.
- DeepSeek-V3 (full): 671B MoE — 400+ GB RAM at Q4 — impractical on consumer hardware. Use the distilled versions instead.
- Ollama command:
ollama run deepseek-r1:7b(uses the Q4_K_M distill by default)
Qwen2.5 Local Models Explained
Qwen2.5 is Alibaba's October 2025 release covering base, Coder, and Vision-Language variants. All base models use a 128K context window and Apache 2.0 license.
- Qwen2.5 7B: 5.5 GB VRAM. Best general-purpose 7B for coding and Chinese text. 74.6% HumanEval outperforms every 7B competitor on code.
- Qwen2.5 14B: 9.5 GB VRAM. The sweet spot for balanced quality vs speed. 82.1% HumanEval, 79.2% MMLU. Best choice for most 12 GB VRAM setups.
- Qwen2.5 32B: 20.5 GB VRAM. 91.5% HumanEval — best coding benchmark score under 48 GB VRAM.
- Qwen2.5-Coder 32B: Same VRAM as base 32B, fine-tuned specifically for code generation and review. Use instead of base when coding is the primary task.
- Qwen2.5 72B: 46 GB VRAM. 86.1% MMLU, 97% HumanEval. Only runs on 48+ GB unified memory (M2/M3 Ultra) or multi-GPU setups.
- Ollama command:
ollama run qwen2.5:14b-instruct-q4_K_M
Apple Silicon vs NVIDIA: Running Both Families
Both DeepSeek distills and Qwen2.5 run well on Apple Silicon via Ollama or llama.cpp with Metal acceleration. The key difference is memory bandwidth.
Use Case Verdicts
One-sentence answer for each common local-LLM use case:
- Math homework / tutoring: DS-R1-Distill-Qwen-7B — 88% MATH-500 outperforms Qwen2.5 7B (62.5%) at the same VRAM
- Code generation / review: Qwen2.5-Coder 32B — 91.5% HumanEval, the highest of any consumer-runnable model
- Chinese-language chat: Qwen2.5 7B — native CJK tokenisation, 30–40% more token-efficient on Chinese text
- Step-by-step analysis / reasoning chains: DS-R1-Distill-Qwen-14B — produces explicit chain-of-thought by default
- General daily assistant (8 GB VRAM): Qwen2.5 7B — more fluent conversation, avoids DeepSeek's over-reasoning on simple tasks
- Private enterprise deployment (China): Qwen2.5 — Apache 2.0 license, Alibaba provenance simplifies CAC compliance documentation
FAQ
Is DeepSeek-R1 the same as the distilled models?
No. DeepSeek-R1 is the 671B mixture-of-experts model requiring server hardware. The distilled versions (7B, 14B, 32B) are separate dense models trained to replicate its reasoning style — these are the practical local-use options.
Do DeepSeek and Qwen use the same VRAM at each parameter size?
Yes, at the same quantisation level. Both 7B models need approximately 5.5 GB at Q4_K_M; both 32B models need 20.5 GB. The hardware choice is about task preference, not VRAM difference.
Can I run DeepSeek-R1 distilled models with Ollama?
Yes. Run ollama run deepseek-r1:7b for the 7B distill or ollama run deepseek-r1:32b for the 32B. Ollama downloads Q4_K_M by default.
Which is better for Chinese text: DeepSeek or Qwen?
Qwen2.5 is significantly better for Chinese text. It uses a purpose-built Chinese tokeniser that is 30–40% more efficient on CJK text. The DeepSeek-R1 distilled models are built on Qwen2.5 weights, so they also inherit reasonable Chinese support, but the base Qwen2.5 models are the primary choice.
Which model should I use for math on 8 GB VRAM?
DeepSeek-R1-Distill-Qwen-7B. It scores 88% on MATH-500 vs 62.5% for Qwen2.5 7B — a 25-point gap — at identical VRAM usage.
Does DeepSeek-R1 comply with China data law if run locally?
Running any model locally means data never leaves your hardware, which satisfies the data residency requirements of China's Data Security Law regardless of model origin. The compliance question is about data handling, not model provenance.
