MacBook Air/Pro M4 (16GB) vs NVIDIA RTX 4070 (12GB) for local LLMs
How the two stack up for running open-source LLMs locally — memory, bandwidth, price, and how many of the 48 tracked models each one can run.
| MacBook Air/Pro M4 (16GB) | NVIDIA RTX 4070 (12GB) | |
|---|---|---|
| Memory | 16.0 GB | 12.0 GB |
| Bandwidth | 120 GB/s | 504 GB/s |
| Price (approx) | $1,199 | $549 |
| LLMs it runs | 19 of 48 | 19 of 48 |
| Best model it runs | Devstral Small 2 24B · 8–12 tok/s | Devstral Small 2 24B · 35–53 tok/s |
Both run the same number of models, but the MacBook Air/Pro M4 (16GB) has more memory (16.0 GB), so it can hold larger models at higher quality. The NVIDIA RTX 4070 (12GB) has more memory bandwidth (504 GB/s), so it generates tokens faster at the same model and quant.
