Key Takeaways
- Laptop: 7–13B models, ~15–25 tok/sec, $1500–3000, portable.
- Desktop: 7B–70B models, 80–150 tok/sec, $1500–4000, stationary.
- Thermal constraints make laptops impractical for sustained inference.
- As of April 2026, both are viable, but for different use cases.
Performance: Laptop vs Desktop
| Hardware | Model Tested | Speed | Thermal Throttling |
|---|---|---|---|
| MacBook Pro 16" M3 Max | — | 25 tok/sec | — |
| Framework Laptop 16" + GPU | — | 45 tok/sec | — |
| Desktop RTX 4070 Ti | — | 80 tok/sec | — |
| Desktop RTX 4090 | — | Impossible (laptop) | — |
Thermal Constraints on Laptops
Laptops have limited cooling. CPU + GPU at full load = high temperature, throttling.
MacBook Pro M3 Max: Thermal throttles after 15–20 minutes of sustained inference.
Gaming laptops: Better cooling, but still throttle after 30–45 minutes.
Solution: Use laptop for short bursts (chat, experimentation), not 24/7 services.
Cost Comparison
| Option | Total Cost | LLM Speed | Cost Efficiency |
|---|---|---|---|
| MacBook Pro 16" M3 Max | — | 25 tok/sec | — |
| MacBook + external GPU enclosure | — | 80 tok/sec | — |
| Desktop RTX 4070 Ti | — | 80 tok/sec | — |
| Desktop RTX 4090 | — | 150 tok/sec | — |
When to Choose Laptop vs Desktop
Choose laptop if:
- You need portability and work from multiple locations.
- You run short inference sessions (chat, experimentation).
- You already own a high-end MacBook or gaming laptop.
When to Choose Desktop
Choose desktop if:
- You run 70B models or need 80+ tok/sec.
- You run services 24/7 (APIs, batch processing).
- You prioritize cost efficiency.
- You want to avoid thermal throttling.
