On October 28, Apple finally put a number on the memory option it promised back in August, and the Mac Studio 512GB RAM price lands at $22,299 with 1TB of storage. On Apple’s order page the build reads “M5 Ultra chip, 36-core CPU, 80-core GPU, 512GB memory,” and the total is roughly what some families spend on a used car.
For the right buyer, this machine is less a luxury and more a shortcut. Here is who should pay, who should not, and why two cheaper Mac Studios might be smarter.
What’s actually new with the 512GB option
August brought the M5 generation to the Mac Studio, in both Max and Ultra flavors. When those models started shipping on September 22, the most memory you could pick was 256GB, even on the Ultra. Apple said a 512GB tier would follow in October, and it is now open for orders.
There is one catch right away. You cannot add 512GB to just any Mac Studio. It is only offered on the highest M5 Ultra build, the one with the 80-core GPU. The entry M5 Ultra (30-core CPU, 64-core GPU) and both M5 Max versions top out lower. If you were hoping to pair a modest chip with a mountain of memory, Apple has closed that door.
Delivery is slow too. Orders placed this week were quoted for late November to early December.
How the Mac Studio 512GB RAM price breaks down
The headline figure makes more sense once you climb the configuration ladder one rung at a time. These are US prices with 1TB of storage unless noted.
| Configuration | Memory | Price |
|---|---|---|
| M5 Ultra, 30-core CPU, 64-core GPU | 96GB | $5,499 |
| M5 Ultra, 36-core CPU, 80-core GPU | 96GB | $6,799 |
| M5 Ultra, 80-core GPU, memory upgrade | 256GB | $10,799 |
| M5 Ultra, 80-core GPU, memory upgrade | 512GB | $22,299 |
| M5 Ultra, 80-core GPU, 16TB storage | 512GB | $29,799 |
Look at the jumps. Going from 96GB to 256GB adds $4,000. Doubling again from 256GB to 512GB adds $11,500. In total, the memory alone is $15,500 on top of the 80-core GPU model. Max out the SSD at 16TB and the bill sits just under $30,000.
So the Mac Studio 512GB RAM price is not really about the computer. Roughly 70 percent of the $22,299 total is the memory upgrade. You are paying for capacity, not for extra CPU or GPU cores, which are identical to the $6,799 model. You can price your own build on Apple’s Mac Studio store page.
Who benefits from 512GB of unified memory
Apple silicon shares one pool of memory between the CPU and GPU. That matters for one group above all: people running large AI models on their own hardware. A big language model has to fit in memory to run well, and 512GB of unified memory lets a single desktop hold models that would otherwise need a rack of graphics cards or a rented cloud server.
- Local AI developers. Anyone building, fine-tuning or testing very large models who wants the work to stay on a machine they control.
- Machine learning researchers. Teams that would otherwise rack up monthly cloud bills can treat the one-time cost as an investment.
- Privacy-bound businesses. Law, health and finance shops that cannot send data to an outside AI service may find a single box easier to approve.
For these buyers, the Mac Studio 512GB RAM price can be cheaper than the alternative. That is the only lens through which $22,299 looks reasonable.
Who can skip it
Almost everyone else. Video editors, photographers, music producers and developers who build apps rather than AI models will not come close to filling 512GB. For that work, the Mac Studio 512GB RAM price mostly buys $11,500 of memory that sits idle.
Heavy pro users are better served by the 96GB or 256GB builds. A common mistake is buying for an imagined future workload rather than the one on the desk today.
The two-Mac alternative to the 512GB Mac Studio
Here is the math that makes the Mac Studio 512GB RAM price awkward for Apple. Two 256GB M5 Ultra Mac Studios cost $21,598 together. That is $701 less than one 512GB unit, and you get two full M5 Ultra chips instead of one.
The machines can be connected with RDMA over Thunderbolt 5 and share supported AI jobs using Apple’s open-source MLX framework. It is not plug and play, though. Getting the pair working takes real setup, and while a large model can be split across both machines’ memory, it is not one unified pool, and the Thunderbolt link is far slower than on-chip memory. Software has to split the work between them.
Our view: if your models are tuned for distributed work and you are comfortable with the setup, two machines give you more compute for less money. If you need one huge model loaded in one place with no fuss, the single 512GB Mac Studio is the cleaner tool, and the Mac Studio 512GB RAM price is the toll for that simplicity.
Scenario by scenario
- You run giant local models daily. The Mac Studio 512GB RAM price is easiest to justify here, since nothing else from Apple holds as much in one place.
- You split AI work across machines already. Look hard at two 256GB units and pocket the $701 difference.
- You edit 8K video or produce music. Stop at 96GB or 256GB. The rest is wasted.
- You need it this month. Pick an in-stock configuration, since the 512GB model ships weeks out.

Frequently asked questions about the 512GB Mac Studio
When will the 512GB Mac Studio ship?
Orders placed in late October were quoted for delivery between late November and early December. Shipping estimates can move, so check the date on Apple’s store before you order.
Can you get 512GB of unified memory with the M5 Max Mac Studio?
No. The 512GB option is only available on the M5 Ultra model with the 36-core CPU and 80-core GPU. The M5 Max and entry M5 Ultra builds top out lower.
Do two linked Mac Studios act like one 512GB Mac?
No. Two 256GB units can share supported AI work over Thunderbolt 5 with tools like MLX, and a model can be split across both machines’ memory, but it is not one unified pool, and software must split the job between them.
Should you pay for the 512GB Mac Studio?
Only if the models you run today will not fit in 256GB, and only if keeping that work on your own desk beats paying a cloud provider every month. Everyone else should treat the Mac Studio 512GB RAM price as a signal of where Apple sees pro AI going, not as a shopping list. The best upgrade for most people is the $11,500 they do not spend.
