Both prices cover complete systems. 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.
The Mac mini M6 (32GB) runs 2 more of the tracked models (51 vs 49), thanks to its 32.0 GB of memory. The Mac mini M6 (32GB) has more memory bandwidth (170 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
