Hardware comparison
MacBook Pro / Mac Studio M4 Max (128GB) vs NVIDIA RTX 3090 (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 MacBook Pro / Mac Studio M4 Max (128GB) runs 11 more of the tracked models (62 vs 51), thanks to its 128.0 GB of memory. The NVIDIA RTX 3090 (24GB) has more memory bandwidth (936 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
