Comparison
NVIDIA DGX Spark vs Mac mini M4 24GB for local LLMs
NVIDIA DGX Spark (115.2GB usable, 273 GB/s) vs Mac mini M4 24GB (18GB usable, 120 GB/s) for local LLMs: capacity decides which models load at all, memory bandwidth decides the speed tier. Verdicts below are computed per model at each machine's best clean quant.
NVIDIA DGX Spark verdicts are beta: fit is physics and holds, but speed tiers aren't calibrated yet for that hardware class.
