What AI models can the Apple M2 Ultra (128 GB) run?
- Unified memory
- 128 GB
- Usable for models
- 96.0 GB
- Memory bandwidth
- 800 GB/s
- FP16 compute
- 27.2 TFLOPS
- Released

macOS lets the GPU use roughly two-thirds to three-quarters of unified memory by default, so we plan around that figure rather than the full 128 GB.

Estimates come from published hardware specs and our open formulas, not from running the model on your machine. Real speed varies with runtime, drivers and settings. Numbers marked “Measured” come from a linked benchmark.
