Apple Mac Studio M5 Ultra 36-core CPU (2026)

What owners say

The strongest evidence for the 36-core CPU/80-core GPU Ultra concerns machines with 256 GB of memory. Tom's Hardware tested that chip with 256 GB and a 4 TB SSD, found stable behaviour through repeated stress runs and used it for large local AI models. Its assessment combines considerable processing capacity with a compact enclosure and unobtrusive cooling, but criticises the cost of memory and storage. Computerworld also used a loaned 256 GB/4 TB machine and describes a powerful desktop that remains relatively quiet in its work. These are not tests of the 96 GB option or our 1 TB SSD. The smaller-memory version has the same chip, but cannot inherit claims about fitting models that need the larger memory pool. Owner accounts add texture to the acoustic verdict. One 80-core GPU/256 GB owner describes a twelve-hour GPU workload with hot exhaust and little noticeable noise; another hears soft airflow and electronic clicks under heavy use. Neither supplies a sound-meter reading, and the storage capacities are unspecified. The reports support its use as a small workstation for demanding jobs, while leaving room for differences between units, rooms and workloads. They do not justify guaranteed silence or treating every configuration as equally capable of running very large models.

For whom

Professionals with sustained compute or local-AI workloads who can match model memory requirements to the selected 96 GB or 256 GB capacity.

Not for

A gaming-first purchase, an expandable workstation, or buyers expecting 96 GB to hold the same models as the reviewed 256 GB machines.
