Specifications and setup
- Memory
- 96 GiB Unified memory
- Connection
- On-chip unified memory; no discrete VRAM pool
- Runtime
- Metal / MLX. Actual usable memory is runtime- and OS-dependent; query recommendedMaxWorkingSetSize rather than treating all RAM as VRAM.
- Bandwidth basis
- Apple-published chip bandwidth; shared CPU/GPU traffic reduces bandwidth available to inference.
- System reserve
- Planner assumption: 25% of installed memory reserved for macOS, other apps and allocation headroom. This is adjustable, not an Apple GPU-allocation guarantee.
