Apple's new Mac Studio tops out at 512GB of memory, and 5,499 dollars
Key takeaways
- Mac Studio M5 Max starts at 2,499 dollars, M5 Ultra starts at 5,499 dollars, both available from September 22
- M5 Max tops out at an 18-core CPU, 40-core GPU and 128GB unified memory with bandwidth up to 614GB per second
- M5 Ultra scales to a 36-core CPU, 80-core GPU and 512GB unified memory, the first Ultra chip with a Neural Accelerator in every GPU core
- Apple claims up to 4.3x the peak AI compute of the M3 Ultra, entirely from the new Neural Accelerator hardware
- 512GB of fast unified memory puts large local AI models within reach of a desktop that plugs into a wall socket rather than a server rack
Apple picked a strange week to make its quietest hardware launch sound like its most consequential one. The new Mac Studio, running either the M5 Max or M5 Ultra chip, became available today, and the headline number is not clock speed or core count. It is memory: up to 512GB of it, unified and fast enough to feed a GPU rather than just a CPU.
Two chips, one very different ceiling
The M5 Max model starts at 2,499 dollars (2,299 dollars for education buyers) and gives you an 18-core CPU split across six super cores and 12 performance cores, alongside a GPU that scales up to 40 cores. Memory bandwidth runs from 460GB/s up to 614GB/s depending on configuration, and every GPU core carries its own Neural Accelerator, Apple's term for dedicated matrix-math hardware sitting next to the shader cores.
Step up to the M5 Ultra and the price jumps to 5,499 dollars (5,099 dollars for education), but so does everything else. You get up to a 36-core CPU, an 80-core GPU, and for the first time on an Ultra chip, a Neural Accelerator inside every one of those GPU cores rather than just a subset. Unified memory tops out at 512GB. Apple's own claim is 4.3 times the peak AI compute of the previous M3 Ultra, a jump that comes almost entirely from the accelerator hardware rather than raw core count.
Why 512GB actually matters
Large local AI models live or die on how much memory sits close to the compute doing the work. A machine that can hold 512GB of unified memory can, in principle, run models that would otherwise need a rack of GPUs and a five-figure power bill. That is the audience Apple is chasing here: researchers, studios and small AI teams who want to run serious models on a desk rather than rent cloud compute by the hour.
For anyone not doing local AI inference at that scale, the practical upgrade is video and 3D work, where the extra GPU cores and memory bandwidth translate directly into faster renders and smoother playback of heavy footage.
Why it matters
The Mac Studio has always been Apple's answer to what if a desktop had laptop efficiency and workstation power. The M5 generation pushes that further into genuinely specialised territory: this is now a machine built around a specific bet that on-device AI workloads are worth dedicating silicon to, at a price that puts it well outside impulse-purchase range. If you are not already sure you need 512GB of unified memory, you almost certainly do not need this machine. If you are, Apple just built the only consumer-adjacent computer that offers it.
