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 NVIDIA DGX Spark (GB10, 128GB) runs 8 more of the tracked models (62 vs 54), thanks to its 128.0 GB of memory. The MacBook Pro / Mac mini M5 Pro (48GB) has more memory bandwidth (307 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
