Mac Studio, M3 Ultra, 256GB, refurbished

1TB of storage, 819GB/s of memory bandwidth, and 248GB of unified memory left for a model once macOS has taken its share. It holds 25 of the 30 models we track.

The cheapest 256GB of unified memory Apple sells in any condition. Apple did not show an original price on this build, so we do not quote a saving against one.
