AMD Ryzen AI Max+ 395 vs Nvidia DGX Spark vs Apple Mac — plus when a GPU tower still beats all three. A practical hardware guide for IT managers, developers, and small-business owners weighing a local LLM machine.

There’s no single winner. The right pick comes down to three numbers — how big a model you need to run (memory capacity), how fast it has to run (memory bandwidth), and which software you depend on (CUDA, ROCm, or Metal). A discrete-GPU tower is fastest but hits a VRAM wall; AMD’s Strix Halo mini PCs give the most memory per dollar on Windows; Nvidia’s DGX Spark adds the CUDA stack at a premium; Apple’s Macs offer high bandwidth and silence without CUDA. An appendix at the end collects what early buyers of the AMD “lunchbox” are actually reporting.
