Hardware comparison
MacBook Pro / Mac mini M5 Pro (48GB) vs Intel Arc B580 (12GB) 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 models and 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 mini M5 Pro (48GB) runs 24 more of the tracked models (54 vs 30), thanks to its 48.0 GB of memory. The Intel Arc B580 (12GB) has more memory bandwidth (456 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
