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.
The NVIDIA DGX Spark (GB10, 128GB) runs 14 more of the tracked models (62 vs 48), thanks to its 128.0 GB of memory. The NVIDIA RTX 4060 Ti (16GB) has more memory bandwidth (288 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
