This spring, Apple made it official: The Mac Pro is dead. When Apple was using Intel processors and AMD GPUs, the idea of an expandable and upgradeable tower made sense. But Apple Silicon chips bring the CPU, GPU, and memory interface all under one roof in a way that makes that sort of upgradeability not just superfluous but impossible. At least not without breaking some of the chips’ key benefits. And as it happens, Apple Silicon’s combination of a fast CPU, solid GPU, and unified memory architecture has made it a good fit for a modern “pro” workload that really pushes high-end hardware: running language models and agents locally. That’s really the core audience for the M5 Ultra Mac Studio, Apple’s tippity-top config that is jumping two processor generations in a single refresh (there was no M4 Ultra, if you recall). The highest-end Studios have always felt like a bit of overkill for most people, but now there’s a particular kind of AI-pilled coder or designer who can legitimately benefit from having this kind of system on their desk. Apple was caught off guard by the demand for these systems from people running software like OpenClaw and running open-weight models locally, which, along with the AI-fueled memory shortage, is why it has been nearly impossible to buy most of these systems for months. That’s the context that the new Mac Studio is launching into. Same design, new hardware The new Mac Studio looks the same as it did when it launched with the M1 Max and M1 Ultra back in 2022. It’s a small, squat box, with the same 7.7-by-7.7-inch footprint as the old Mac mini, but it’s taller. Both the Max and Ultra variants of the Studio look the same, but the M5 Ultra version weighs two pounds more because it has heavier but more-conductive copper in its heatsink to help cool the more powerful chip.
