🧠Minimum Specification for Gemma 4
Here are the minimum specifications required to run the Gemma 4 model (locally or for experimentation):
🧠1. CPU (No GPU / Basic Mode)
- Processor: Minimum 4-core (Intel i5 / Ryzen 5 or higher)
- RAM:
- 8 GB → very limited (only small / quantized models)
- 16 GB → more stable for smaller models
- Storage: SSD (at least 20–50 GB free space)
👉 Suitable for:
- Lightweight testing
- Simple chat (small models only, e.g., 2B–7B)
⚡ 2. GPU (Recommended)
- Minimum VRAM:
- 4 GB VRAM → only very small (quantized) models
- 8 GB VRAM → suitable for 2B–7B models
- 16 GB+ VRAM → smoother and faster performance
Example GPUs:
- NVIDIA GTX 1650 (absolute minimum)
- RTX 3060 (sweet spot)
- RTX 4060 / 4070 (better performance)
👉 Suitable for:
- Fast inference
- Real-time AI chat
- AI coding experiments
📦 3. Model Versions vs Requirements
| Gemma Model | Minimum RAM | Minimum VRAM | Notes |
|---|---|---|---|
| 2B | 8–16 GB | 4–6 GB | Lightweight |
| 7B | 16–32 GB | 8–12 GB | Standard |
| Larger models | 32 GB+ | 16 GB+ | Heavy |
🧰 4. Supporting Software
- OS: Linux / Windows (WSL) / macOS
- Python: 3.10+
- Frameworks:
- PyTorch
- Transformers (Hugging Face)
- Optional:
- Ollama (easier local usage)
- CUDA (for NVIDIA GPUs)
🚀 Quick Summary
- Bare minimum (runs only)
→ 8 GB RAM + CPU (slow) - Comfortable use
→ 16 GB RAM + 8 GB GPU - Optimal setup
→ 32 GB RAM + 16 GB GPU
