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 differ. These estimated speeds are not a like-for-like comparison. Estimates use 4,096 context tokens, llama.cpp and one stream.
The MacBook Air / Mac mini M4 (24GB) runs 19 more of the tracked models (49 vs 30), thanks to its 24.0 GB of memory. The NVIDIA RTX 4070 (12GB) has more memory bandwidth (504 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
