Mac mini M6 (32GB) vs NVIDIA RTX 5090 (32GB) for local LLMs
How the two stack up for running open-source LLMs locally — memory, bandwidth, price, and how many of the 64 tracked models each one can run.
| Mac mini M6 (32GB) | NVIDIA RTX 5090 (32GB) | |
|---|---|---|
| Memory | 32.0 GB | 32.0 GB |
| Bandwidth | 170 GB/s | 1792 GB/s |
| Price (approx) | $1,299 | $4,399 |
| LLMs it runs | 47 of 64 | 48 of 64 |
| Best model it runs | Qwen3.8 27B · 10–15 tok/s | Qwen3.8 27B · 48–72 tok/s |
The NVIDIA RTX 5090 (32GB) runs 1 more of the tracked models (48 vs 47). With the same nominal memory, more of it is usable for model weights on this architecture. The NVIDIA RTX 5090 (32GB) has more memory bandwidth (1792 GB/s), so it generates tokens faster at the same model and quant.
