Apple's high-end system-on-chip pairing two M3 Max dies, used in the Mac Studio with up to 192GB unified memory and ~800GB/s bandwidth.
Apple's M5 Ultra Mac Studio starts at $5,499 and reached $12,299 as tested, and the reviewer running local agents on it every day says the most expensive Anthropic subscription would still have cost less for years.

The review's own processor numbers run from 8 to 22 percent, and its case for replacing an M4 Max or M3 Ultra Studio rests on disk throughput. Memory and storage are soldered, so that gain arrives only with a whole new machine.
Reality
The 2025 configurations are gone from the store rather than fading out, which turns a refresh most shops would have taken at renewal into a purchase they have to justify on this quarter's numbers.
Reality
The quad-die design breaks the recipe Apple has used for Ultra chips since M1. Interconnect goes to 4.4TB/s from 2.5TB/s, while the 512GB memory ceiling and the 80 GPU cores do not move.
Reality
The bandwidth gap is 4.4x and the capacity gap is 4x, which is why these two boxes are not really competing. One decides whether a model fits; the other decides whether it is usable.
