Hardware comparison
MacBook Air/Pro M5 (16GB) 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.
Both estimated speeds use the same model and quant shown above. Estimates use 4,096 context tokens, llama.cpp and one stream.
Both run the same number of models, but the MacBook Air/Pro M5 (16GB) has more memory (16.0 GB), so it can hold larger models at higher quality. 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.
