How the two stack up for running open-source LLMs locally — memory, bandwidth, price, and how many of the 18 tracked models each one can run.
| MacBook Pro M4 Pro (48GB) | NVIDIA RTX 4090 (24GB) | |
|---|---|---|
| Memory | 48.0 GB | 24.0 GB |
| Bandwidth | 273 GB/s | 1008 GB/s |
| Price (approx) | $2,399 | $1,599 |
| LLMs it runs | 15 of 18 | 15 of 18 |
| Best model it runs | Gemma 4 31B · 9–13 tok/s | Gemma 4 31B · 33–50 tok/s |
Both run the same number of models, but the MacBook Pro M4 Pro (48GB) has more memory (48.0 GB), so it can hold larger models at higher quality. The NVIDIA RTX 4090 (24GB) has more memory bandwidth (1008 GB/s), so it generates tokens faster at the same model and quant.
