Mac Studio With 512GB of Memory Is Now 22,299 USD: Who It's For
Apple made the 512GB M5 Ultra Mac Studio orderable at 22,299 USD. Why unified memory this large exists, who needs it, and why almost nobody should buy it.

What Apple actually did
On October 28 Apple quietly made the Mac Studio's biggest memory configuration orderable. The M5 Ultra model can now be specified with 512GB of unified memory, priced at 22,299 USD. Apple announced the M5 Max and M5 Ultra Mac Studio configurations in August and said at the time that a 512GB option would follow later; this week it did. There was no event, no press release fanfare, just a configuration page that went live alongside the MacBook Pro launch. For the audience this machine exists for, that is bigger news than any laptop.
Why 512GB of memory matters
Unified memory is the Mac's defining architectural advantage for local AI work. A model has to fit in memory to run, and the size of the model determines capability. 512GB is enough headroom to load open-weight models at scales that simply cannot run on a normal desktop, which is why the people buying this configuration are not editing video, they are running inference locally. Apple's own positioning of the Mac Studio as an AI workstation makes more sense with each memory step, and this is the largest one it has shipped.
The price tells you who it is for
22,299 USD for the 512GB configuration is roughly the price of a used car in Canada, and Apple is not pretending otherwise. Compare it to alternatives: a high-end workstation with comparable memory would come from server hardware, with server noise and server power draw. A Mac Studio sits on a desk, runs quietly, and draws a fraction of the power. For a studio or a research team that needs a large model resident in memory all day, the math can work. For everyone else, this is a curiosity.
Memory prices are the context
The reason this configuration arrives late and costs what it does is memory supply. Apple does not manufacture DRAM, and industry-wide memory pricing has climbed sharply enough this year that several vendors have raised prices or cut configurations. A 512GB unified memory option is one of the most memory-intensive configurations Apple sells, so its price reflects both the silicon and the market it was bought in. That also explains why the 512GB option appeared months after the Mac Studio itself.
What it means for Canadian buyers
Apple Canada lists the Mac Studio lineup separately and Canadian pricing does not track a straight conversion of US figures. If you are considering a configuration at this level, order through apple.com/ca and confirm the exact memory, storage and delivery estimate, because these builds are made to order and lead times stretch. Business pricing and education pricing do not apply to this class of machine, but a lease or a business purchase through an Apple reseller can change the effective cost substantially.
The honest verdict
Almost nobody should buy this. The people who should are the ones who already know exactly which model they need to keep resident and how much it costs them per hour to wait for it to load. For those buyers, 512GB on a quiet desktop workstation is a legitimate tool, and the Mac Studio's efficiency at sustained load makes it a reasonable choice. For the rest of us, it is a useful reminder that the Mac Studio's ceiling keeps rising while its base price stays within reach of a serious hobbyist.
Frequently Asked Questions
It is also worth separating two different buyers who both want memory. The first runs inference on models that must be resident, where capacity is the whole point. The second batch-processes training or rendering jobs where throughput matters more than capacity, and for those users a cluster of cheaper machines often beats one enormous one. Apple's pitch lands hardest with the first group, and that is the group this configuration is priced for.
One practical consideration for anyone seriously considering this machine: unified memory is not upgradeable after purchase, and the Mac Studio's internals are not user-serviceable in any meaningful way. That makes the memory decision permanent for the life of the machine, which is a different calculation than buying a workstation you can expand later. If there is any chance you will need more than your current plan, buy the tier above, because the only upgrade path is a new computer.
How much does the 512GB Mac Studio cost?
Apple lists the M5 Ultra Mac Studio with 512GB of unified memory at 22,299 USD. Canadian pricing should be confirmed on apple.com/ca.
When did the 512GB option become available?
Apple announced the M5 Max and M5 Ultra Mac Studio in August 2026 and said a 512GB configuration would follow. It became orderable on October 28, 2026.
Who needs 512GB of unified memory?
Buyers running large open-weight AI models locally, where the model must fit in memory to run. For video editing, software development or general professional work, far less memory is sufficient.
Is the Mac Studio M5 Ultra a good value?
Compared to server-class workstations with similar memory, the Mac Studio is quieter, more efficient and often cheaper. Compared to a normal desktop it is enormously expensive, so its value depends entirely on whether you need the memory ceiling.
