CPU vs GPU for Local AI: What Should You Actually Buy?
This is the biggest decision in a home AI lab build. Start CPU-only? Or jump straight to a GPU machine?
When a CPU-Only Mini PC Is Enough
- Running 7B–8B models
- Single-user environment
- Light lab + assistant workflows
- Budget under $1000
Modern Ryzen mini PCs with 32–64GB RAM handle most self-hosted workflows comfortably.

When You Need a GPU
- Large context models
- Multi-user environment
- Heavy inference workloads
- Speed-critical workflows
A GPU dramatically improves inference speed and supports larger models, but increases cost and power usage.

Real-World Recommendation
Start CPU-only. Upgrade to GPU only if your workflow demands it.
Most builders overestimate their needs.
