NVIDIA RTX 3080 - 10GB usable
Popular but 10GB VRAM is tight. Fine for 7B models, struggles beyond that.

For AI / LLM Use
Limited VRAM restricts you to 7B quantized models.
What Models Can It Run?
- 7B Q6_K, 14B Q3_K (tight)
- 7B Q4_K_M only
Estimated Performance
Generation: ~57 tokens/sec
Prefill: ~536 tokens/sec
Recommended Quantisations
- Q4_K_M for 7B models
- Q3_K for larger experiments
Pros & Cons
Pros
- Ampere architecture: broad CUDA software support
- Consumer card: easy to install, display output
Cons
- Moderate memory bandwidth: not the fastest for inference
- 320W TDP: high power draw
Community Verdict
- r/LocalLLaMA
10GB is tight for AI. Can run 7B models but you will hit VRAM limits quickly with larger models.
