Hardware comparison
Mac mini M6 (24GB) vs NVIDIA RTX 4090 (24GB) for local LLMs
How the two stack up for running open-source LLMs locally — memory, bandwidth, price, and how many of the 69 tracked models each one can run.

These prices cover different purchases: a GPU card excludes its required host PC; a complete system includes the machine. No price winner is marked. Prices are approximate catalog estimates; check current configurations and prices before buying.
The recommended quants differ. These estimated speeds are not a like-for-like comparison. Estimates use 4,096 context tokens, llama.cpp and one stream.
The NVIDIA RTX 4090 (24GB) runs 2 more of the tracked models (51 vs 49). With the same nominal memory, more of it is usable for model weights on this architecture. The NVIDIA RTX 4090 (24GB) has more memory bandwidth (1008 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
