Apple’s latest desktop lineup draws a sharper line between affordable local AI work and maximum performance. The Mac Studio with M5 Ultra offers up to 512GB of unified memory for running very large AI models on a desk. The smaller Mac mini with M6 delivers strong everyday performance, but its memory ceiling makes it a more limited option for demanding generative AI tasks.
The reviews from Steve Dent at Engadget and Brandon Hill at Tom’s Hardware show how Apple is positioning its desktop hardware as organizations and creators look for alternatives to cloud based AI services.
Mac Studio prioritizes memory for local models
The M5 Ultra version of the Mac Studio starts at $5,500 and can be configured with up to 512GB of unified memory. Unified memory is shared by the CPU, graphics processor, and Neural Engine. For AI users, that large shared pool matters because it can hold models that would not fit into the memory of many conventional desktops.
Dent reports that Apple promotes the system for locally running frontier class models with billions of parameters. Apple also says four M5 Ultra Mac Studios can be connected in a Thunderbolt 5 cluster to process AI work three times faster than one machine. That setup would be aimed at teams with unusually large budgets and workloads, rather than individual users.
In testing, the M5 Ultra produced the highest Neural Engine score Dent had seen in Geekbench AI. Using Mac Whisper, an application for speech transcription, it processed a 70 minute podcast in 18 seconds. That type of speed could be useful for media teams that regularly turn interviews, meetings, or video recordings into searchable text.
The system also offers six Thunderbolt 5 ports, including two on the front. These connections support data rates of up to 120 Gbps, which can help users work with fast external storage and other high bandwidth equipment. However, compatible accessories remain expensive.
Price is the central drawback. Dent’s tested system, with 256GB of memory and 2TB of storage, cost $11,299. He finds that the M5 Ultra delivers roughly 20 to 30 percent higher performance than the earlier M3 Ultra in many tests, while costing substantially more. Compared with the M5 Max Mac Studio, AI benchmark gains were closer to 10 percent in some synthetic tests.
Mac mini offers a lower entry point, with limits
The M6 Mac mini begins at $899 with 16GB of unified memory and 256GB of storage. It is much cheaper than the Mac Studio, but it is no longer the unusually low cost Mac desktop it once was. Hill notes that the previous M4 model started at $599.
For routine AI assisted work, such as using Apple Intelligence features, drafting tools, image applications, transcription, and smaller local models, the Mac mini may be sufficient. Its M6 chip improves single core performance, storage speeds, networking, and wireless connectivity. It includes Wi Fi 7 and Bluetooth 6.
Yet the M6 model tops out at 32GB of memory. The M5 Pro configuration reaches 64GB, but prices rise quickly. A fully configured M5 Pro Mac mini can cost $6,599, which puts it close to Mac Studio territory without the M5 Ultra’s far higher memory capacity.
For most content professionals, the choice comes down to model size and frequency of use. The Mac mini is better suited to AI features embedded in everyday applications and occasional local experiments. The Mac Studio M5 Ultra is built for people who need to process large models, extensive media libraries, or repeated transcription and generation workloads without sending data to a cloud service. Another option not covered by these reviews: the Mac Studio with M5 Max processor starting at $2,499 in the U.S.
