Node Kits
Apple Mac Studio M5 Ultra
5/5
From $5,499
Up to 512GB of unified memory at 1.2TB/s — double the M3 Ultra ceiling, and the first single silent desktop that holds frontier-scale MoE models entirely in memory. This is a capability purchase, not a value one: nothing else in the Apple lineup comes close, and nothing else needs to.
