Apple has introduced a 512GB unified memory option for its M5 Ultra Mac Studio, allowing professionals to configure the desktop with half a terabyte of RAM for demanding workloads.
However, the upgrade comes at a substantial cost. The 512GB memory configuration adds $15,500 to the price of the computer, bringing an M5 Ultra model with the highest CPU and GPU configuration to approximately $22,299 before additional storage upgrades.
Customers who also select the maximum 16TB internal SSD configuration could end up paying approximately $29,800.
The new configuration is primarily intended for professionals working with large AI models, complex simulations, and demanding creative applications that require substantial memory capacity.
Mac Studio M5 Ultra Offers Up to 512GB Unified Memory
Apple's latest Mac Studio features the M5 Ultra processor, with a high end configuration offering a 36 core CPU and an 80 core GPU.
The reported configuration starts at approximately $6,800 with 96GB of unified memory and 1TB of storage.
Upgrading the memory to 512GB increases the price significantly, while selecting 16TB of internal storage adds another $7,500.
| Configuration | Reported price |
|---|---|
| M5 Ultra with 96GB RAM and 1TB SSD | $6,800 |
| M5 Ultra with 512GB RAM and 1TB SSD | $22,299 |
| M5 Ultra with 512GB RAM and 16TB SSD | Approximately $29,800 |
| M5 Max with 36GB RAM and 512GB SSD | $2,499 |
These figures reflect the reported US configurations before applicable taxes.
The large price difference illustrates how significantly Apple's memory and storage upgrades can increase the cost of its professional desktop computers.
Why 512GB Unified Memory Matters for Local AI
One of the main advantages of Apple's unified memory architecture is that the CPU and GPU can access the same memory pool.
This arrangement can be useful for local AI workloads that require more memory than conventional consumer graphics cards provide.
Large language models containing billions of parameters often require substantial memory capacity, particularly when running locally without relying on cloud infrastructure.
With 512GB available, the Mac Studio could accommodate larger models and datasets that would otherwise require specialized hardware or multiple computing devices.
The configuration may also benefit professionals working with complex visual effects, high resolution video production, and scientific simulations.
However, additional memory does not automatically guarantee faster performance. Actual results depend on processor capabilities, memory bandwidth, software optimization, and workload requirements.
Apple's $2,499 Mac Studio Remains a More Affordable Option
For buyers who do not need hundreds of gigabytes of unified memory, Apple also offers a considerably cheaper Mac Studio configuration.
The M5 Max model reportedly starts at $2,499 with 36GB of RAM and 512GB of storage.
That configuration should be more appropriate for many everyday professional tasks, including photo editing, software development, and conventional video production.
The 512GB M5 Ultra model is better suited to organizations and professionals whose applications can make practical use of its unusually large memory capacity.
With local AI computing becoming increasingly important, Apple's latest configuration provides another option for running memory intensive workloads directly on a desktop computer.
Its nearly $30,000 maximum reported price, however, makes it a specialized purchase rather than a practical upgrade for most consumers.
