Desktop AI boxes
Unified-memory machines built to run models locally: DGX Spark and its GB10 twins, Mac Studio, Strix Halo desktops. Ranked by memory, priced live.
Memory ladder
Ranked by memory unless you sort by speed or price, because memory decides what fits. Bars are to scale within each list: solid for dedicated VRAM, hatched for unified memory shared with the CPU. The speed column is the estimated decode rate for the model and quant you pick, for one user with 8K of context.
