The order blocker that kept a high-end Mac Studio option from real buyers has finally been lifted: Apple has opened the 512GB memory configuration on the M5 Ultra Mac Studio months after its August 2026 introduction, and the consumer decision now hinges on whether the upgrade price fits a real workstation need rather than curiosity.

When Apple introduced the Mac Studio family with M5 Ultra and M5 Max models in August 2026, the 512GB memory option was mentioned only as a future configuration and was effectively delayed for shoppers who wanted to build a machine with that much memory. That footnote gap lasted months after launch, so buyers who saw the spec sheet could not choose it at checkout. The new development is that the previously delayed 512GB build is now open for pre-order, and the configuration has been described as possibly the most powerful Mac ever.
For ordinary shoppers, the important point is not only that the option exists, but how tightly it is tied to other upgrades. The 512GB memory option is not offered across the whole M5 Ultra range; it is available only when the machine is configured with the 36-core CPU and 80-core GPU version. That means the top-memory conversation is also a CPU and GPU configuration conversation.
| Buyer scenario | Relevant Apple configuration | Price anchor | What to notice |
|---|---|---|---|
| Entry M5 Ultra Mac Studio | 96GB memory, 1TB storage, 30-core CPU, 64-core GPU | $5,499 | Starting point before the major memory upgrade |
| Higher CPU/GPU step-up | 36-core CPU, 80-core GPU | Adds $1,300 | Required path for the 512GB memory option |
| Maximum memory upgrade | 512GB memory | Adds $15,500 | The delayed configuration that is now orderable |
| Maximum storage upgrade | 16TB storage | Adds $7,500 | Separate from the memory surcharge |
| Top price cited at launch | Highest configuration discussed in August 2026 | $18,299 | Earlier maximum figure from the launch period |
| Top price after opening 512GB orders | Current fully specced example | $29,799 | Now the highest cited price for this Mac Studio build |
Yes. Apple is taking pre-orders for the previously delayed 512GB configuration on the M5 Ultra Mac Studio.
No. Only the model configured with the 36-core CPU and 80-core GPU can select the 512GB memory option.
The 512GB memory upgrade is priced at $15,500.
The available facts cite a current top-build price of $29,799, compared with the $18,299 maximum figure discussed around the August 2026 launch.
The expectation is that it may not sell out as rapidly as iPhone Duo, so urgency is driven by workflow need rather than scarcity.
This update closes a real gap in Apple’s Mac Studio lineup, because a configuration that was only footnoted months after launch can now be purchased. For most buyers, the M5 Ultra Mac Studio with 96GB memory and 1TB storage remains the rational starting point; the 512GB upgrade is a narrowly targeted, high-cost path that only makes sense when a buyer can justify the 36-core CPU, 80-core GPU requirement and the $15,500 surcharge on top of the machine’s total price.
