Both prices cover complete systems. 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 M5 Max (128GB) runs 11 more of the tracked models (62 vs 51), thanks to its 128.0 GB of memory. The MacBook Pro / Mac Studio M5 Max (128GB) has more memory bandwidth (614 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
